Step 6 Select the source server you want to migrate.

1. On the Task Management page, click Create Task.The Create Migration Task page is displayed.

2. For step Select Source Server, set basic parameters for the migration task.3. Set Task Name.

– The default format of a task name is as follows: sms_task_xxx, where xxxindicates the name of the source server. If you want to use the defaulttask name, do not change this parameter. Task names cannot be morethan 20 characters long. If the task name contains more than 20characters, SMS selects the first 20 characters as the task name bydefault.

– You can also customize the task name.4. In the source server list, select the source server to be migrated.

NO TE

You can create a migration task only when Connection Status of the source server isConnected and Source Server Check Result is Passed.

Step 7 Configure advanced settings.

1. Click next to Advanced Settings and configure advanced settings.2. Set Migration Rate. The migration will generate a large amount of traffic. A

lot of bandwidth will be consumed. To reduce the impact on services:– For Linux server migration, restricting the speed of the Network Interface

Cards (NICs) on the target ECSs can reduce the impact on services on thesource server.

The value of Migration Rate must be an integer ranging from 0 to 1000.– You can enter 0 or leave this field blank to remove migration speed

limits. In this case, the migration speed is the network speed between thesource servers and the target ECSs.

– If the migration rate you configure is greater than the network speedavailable between the two servers, then the actual speed of themigration will depend on the speed of the network connection.

3. Set Migration Process Priority. Set the process priority of the Agent on thesource server.– If this parameter is set to High, the source server preferentially allocates

resources (such as CPU time slice, memory, and disk I/O) to the Agentprocess.

– If this parameter is set to Medium, the source server allocates resources(such as CPU time slice, memory, and disk I/O) to the Agent processbased on the default settings.

– If this parameter is set to Low, the source server preferentially allocatesresources (such as CPU time slice, memory, and disk I/O) to processesthat are not Agent processes.

4. Set Action on Target ECS After Migration.– If this parameter is set to Stop, the target ECS will shut down after the

migration is complete.



– If this parameter is set to Start, the target ECS will continue to run afterthe migration is complete.

Step 8 Select a target ECS.

1. Click Next.

The Select Target ECS page is displayed.

2. Select the region and project where the target ECS belongs.

Each region has a default project whose project name is the same as the region code.For example, the region code of region CN North-Beijing1 is cn-north-1, and thedefault project name is cn-north-1. However, the project name is not displayed on themanagement console.

– If you select the region and do not select a project, the default project in the regionis selected for you.

– If you do not select a region, the region and project you selected last time through

are used for migration.

Figure 3-44 Regions and projects

3. Set Network Type.

– Internet (default)

If you select this option, an EIP must be assigned to the target ECS.

– Private line or VPN

You need to create a private line or VPN connection between the sourceserver and the VPC subnet where the target ECS is located.

NO TE

If the source and target ECSs are in the same VPC, set Network Type to Privateline or VPN.

4. Select a target ECS.

– Each object list file cannot exceed 100 MB.– The object list file must be a .txt file, and ContentType in the metadata of the file

must be text/plain.– The object list file must be in UTF-8 without byte order mark (BOM).– Each line in the object list file can contain only one object name, and the object

name must be URL encoded.– Spaces are not allowed in each line in the object list file. Spaces may cause

migration failures because they may be mistakenly identified as object names.– The length of each line in the object list file cannot exceed 65,535 characters, or

the migration will fail.– ContentEncoding cannot be set in the metadata of the object list file, or the

migration will fail.– Archive data can only be accessed and obtained by OMS after it is restored. If the

object list files are archive, manually restore them before migration.

● Object Name PrefixEnter the name or prefix of objects to be migrated. The system will

automatically list the matched data. You can click to delete the data thatdoes not need to be migrated from the list.

NO TE

If no object names or name prefixes are specified, all objects in the source bucket willbe migrated.

● Specified URL ListGenerally, this setting is used to migrate HTTP/HTTPS source data by selectinga URL list file. You need to write the URL of the files to be migrated and their



destination object names into a URL list file and store the file in an OBSbucket on HUAWEI CLOUD. OMS migrates all objects in the specified URL listfile.

a. Select List File Bucket (HUAWEI CLOUD).

NO TE

▪ The buckets listed are the buckets obtained by entering the destination AKand SK in Step 3.2.

▪ If the bucket used for storing object list files is not located in the same regionas the destination bucket, you cannot select the object list files.

▪ For security purposes, if the migration source supports both HTTP and HTTPS,you are advised to use HTTPS during the migration. If HTTP is used, data maybe eavesdropped on, tampered with, or vulnerable to man-in-the-middle orreplay attacks.

▪ URL redirection is not supported.

b. Click Select next to the URL List File area, select the target URL list files,and click OK.

NO TE

▪ Each URL list file cannot exceed 100 MB.

▪ The URL list file must be a .txt file, and ContentType in the metadata of thefile must be text/plain.

▪ The URL list file must be in UTF-8 without BOM.

▪ Each line in the URL list file can contain only one URL and one destinationobject.

▪ The length of each line in the URL list file cannot exceed 65,535 characters, orthe migration will fail.

▪ ContentEncoding cannot be set in the metadata of the URL list file, or themigration will fail.

▪ In the URL list file, each line uses a tab character (\t) to separate the URLfrom the destination object name. The format is [URL][tab character][destination object name]. The destination object name is URL encoded. Forexample:

http://xxx.obs.myhuaweicloud.com/doc/file1.txt doc%2f%e6%96%87%e4%bb%b61.txt

http://xxx.obs.myhuaweicloud.com/doc/thefile2.txt doc%2fthefile2.txt

http://xxx.obs.myhuaweicloud.com/the%20file.txt the%20file.txt

http://xxx.obs.myhuaweicloud.com/the%20file2.txt the+file2.txt

http://xxx.obs.myhuaweicloud.com/doc/thefile.txt doc/thefile.txt

In the preceding examples, after the files represented by the URLs are copiedto the destination bucket, the objects are named doc/doc/thefile2.txt, thefile.txt, the file2.txt, and doc/thefile.txt.

▪ Spaces are not allowed in each line in the URL list file. Spaces may causemigration failures because they may be mistakenly identified as object names.



Step 6 (Optional) Set Source Parameters.

Parameters described in Table 3-8 are only available if the source cloud serviceprovider offers the related functions.

Table 3-8 Source parameters


Use SourceCustom DomainName

If the default domain name cannot meet your migrationrequirements, then if the source cloud service providersupports custom domain names, you can use a sourcecustom domain name to download data to reducedownloading fees.NOTE

If the source cloud service provider is Qiniu Cloud, this option isselected by default to ensure a smooth migration because QiniuCloud has restrictions on default domain names.

If you select this option, complete the following settings:1. Select a transmission protocol for Transfer Protocol.

NOTEHTTPS is more secure than HTTP and is recommended.

2. Enter a custom domain name of the bucket for CustomBucket Domain Name.

3. If you use the CDN authentication provided by thesource cloud service provider, select Enable CDNAuthentication and configure the authentication typeand keys.NOTE

– You can use CDN authentification only after configuringCDN by referring to documents of the source cloud serviceprovider.

– The fees generated for using CDN on the source platformare billed by the source cloud service provider.

– URI redirection is not supported.

4. Click Check to check whether the configuration iscorrect.– If the configuration fails to pass the check, click

Details to view the failure causes.– If the configuration passes the check, complete other

migration configurations.




Archive DataRestoration

Only restored archive data can be migrated. You can selectthis option if your source cloud service provider supportsautomatic restoration of archive data.● Option selected

The system automatically restores and migrates archiveobjects in the migration task. If an archive object fails tobe restored, the system records it in the list of objectsthat failed to be migrated and continues to migrateother objects in the migration task.

● Option not selectedThe system directly records archive objects in the list ofobjects that failed to be migrated and continues tomigrate other objects in the migration task.

NOTE● The following cloud service providers can automatically restore

archive data: HUAWEI CLOUD, Alibaba Cloud, Kingsoft Cloud,and Tencent Cloud.

● It takes at least a minute to restore an archive object. Thelarger the archive object is, the longer it takes to restore it, butif an archive object cannot be restored within three minutes,the restoration fails. The time needed depends on the cloudservice provider. For details, see related documents of thespecific cloud service provider.

● Two types of fees are generated during archive data restoration:fees for API calls and fees for archive data retrieval. These feesare billed by the source cloud service provider.

● After restoration, archive objects will be in restored state for acertain period of time. During this period, objects can bedownloaded or accessed. After this period expires, archiveobjects need to be restored again for migration. For detailsabout how long they stay in the restored state, see relateddocuments from the cloud service provider.

● After the object storage data is migrated from the sourceplatform to HUAWEI CLOUD, the storage class of the migrateddata must be the same as that of the destination bucket.

Step 7 Click Show next to Advanced Settings to expand the advanced parameters.

Step 8 (Optional) Configure advanced parameters.

Table 3-9 Parameters in Advanced Settings


Data Encryption If you select KMS, migrated data is encrypted beforebeing stored to the destination OBS buckets.NOTE

Using KMS to encrypt migrated data may decrease themigration speed by about 10%.This option is only available if KMS encryption is supported inthe current region.




Failed Object Record Specifies whether to record the objects that failed to bemigrated.● Set to No

The system does not record the objects that fail tobe migrated. If the migration fails and needs to beretried, all objects in the source bucket need to betransmitted again.

● Set to YesThe system will record the objects that failed to bemigrated. If the migration fails and needs to beretried, only the failed objects need to betransmitted again.

NOTEThe objects that fail to be migrated are recorded in a filenamed after the task name. For both a single migration taskand a migration group task, the files are uploaded to theoms/failed_object_lists/ directory of the destination bucket.This file contains information about the failed migration tasks,including the failure cause, occurrence time (local UTC), URL-encoded names of the objects fail to be migrated, non-URL-encoded names of the objects fail to be migrated, and errorcodes returned by source SDKs.This file is stored in the destination bucket after the objects inthe file are successfully retransmitted. If you do not need thefile, delete it manually.




Archive DataRestoration

Only restored archive data can be migrated. You canselect this option if your source cloud service providersupports automatic restoration of archive data.● Option selected

The system automatically restores and migratesarchive objects in the migration task. If an archiveobject fails to be restored, the system records it inthe list of objects that failed to be migrated andcontinues to migrate other objects in the migrationtask.

● Option not selectedThe system directly records archive objects in the listof objects that failed to be migrated and continuesto migrate other objects in the migration task.

NOTE● The following cloud service providers can automatically

restore archive data: HUAWEI CLOUD, Alibaba Cloud,Kingsoft Cloud, and Tencent Cloud.

● It takes at least a minute to restore an archive object. Thelarger the archive object is, the longer it takes to restore it,but if an archive object cannot be restored within threeminutes, the restoration fails. The time needed depends onthe cloud service provider. For details, see relateddocuments of the specific cloud service provider.

● Two types of fees are generated during archive datarestoration: fees for API calls and fees for archive dataretrieval. These fees are billed by the source cloud serviceprovider.

● After restoration, archive objects will be in restored statefor a certain period of time. During this period, objects canbe downloaded or accessed. After this period expires,archive objects need to be restored again for migration. Fordetails about how long they stay in the restored state, seerelated documents from the cloud service provider.

● After the object storage data is migrated from the sourceplatform to HUAWEI CLOUD, the storage class of themigrated data must be the same as that of the destinationbucket.

Incremental Data Specifies whether to filter source objects to bemigrated by time.● If this option is set to No, source objects are not

filtered by time.● If this option is set to Yes, only the source objects

that are modified after the specified time are

migrated. You need to click to specify the time.




Traffic Limit Set the maximum bandwidth for the migration task inspecified time segments.● If you do not need to limit migration traffic, select

No.● If you need to limit migration traffic, select Yes.

Perform the following steps to set traffic limits:1. Click Add Rule.

A traffic limiting rule is displayed.2. Specify Start Time, End Time, and Maximum

3.8.4 Creating a Migration Task Group

ScenariosThis section describes how to create a task to migrate your object data.

Prerequisites● You have obtained the AK/SK pairs for the source and destination platform

accounts.– The source platform account needs the following permissions:

▪ list Bucket

▪ get BucketLocation

▪ list Object

▪ head Object

▪ get Object

For details about how to obtain these permissions, contact the sourcecloud service provider.You use the list Bucket and get BucketLocation permissions to select abucket before the migration. If a bucket name is already specified, you donot need to configure these permissions.

– The destination platform account needs the following permissions:

▪ OMS Administrator

▪ OBS OperateAccess

For details about how to obtain the permissions, see Creating a Userand Granting OMS Permissions.

● You have created an OBS bucket on HUAWEI CLOUD.● You have registered an account on HUAWEI CLOUD and completed real-name

authentication.

Step 3 Follow the operations provided in Creating a Migration Task, choose source anddestination buckets, set task parameters, and confirm the information. Start themigration.

NO TE

● When selecting a migration method, you can only select Object Name Prefix orSpecified URL List Folder.

● If you select Object Name Prefix:

The objects to be migrated are recorded in a .txt file, and each migration task has a listfile. The storage path of the files is oms/taskgroup/ in the destination bucket. These listfiles will be retained after the migration, and you can manually delete them.

● If you select Specified URL List Folder:

– The URL list directory cannot be the root directory.

– The URL list directory must contain only .txt files.

– The total number of files in the URL list directory cannot exceed 2000.

– The size of one URL list file cannot exceed 100 MB.

– The URL list file must be a .txt file, and ContentType in the metadata of the filemust be text/plain.

– The URL list file must be in UTF-8 without BOM.

– Each line in the URL list file can contain only one URL and one destination object.

– The length of each line in the URL list file cannot exceed 65,535 characters, or themigration will fail.

– ContentEncoding cannot be set in the metadata of the URL list file, or themigration will fail.

– In the URL list file, each line uses a tab character (\t) to separate the URL from thedestination object name. The format is [URL][tab character][destination objectname]. The destination object name is URL encoded. For example:

http://xxx.obs.myhuaweicloud.com/doc/file1.txt doc%2f%e6%96%87%e4%bb%b61.txt

http://xxx.obs.myhuaweicloud.com/doc/thefile2.txt doc%2fthefile2.txt

http://xxx.obs.myhuaweicloud.com/the%20file.txt the%20file.txt

http://xxx.obs.myhuaweicloud.com/the%20file2.txt the+file2.txt

http://xxx.obs.myhuaweicloud.com/doc/thefile.txt doc/thefile.txt

In the preceding examples, after the files represented by the URLs are copied tothe destination bucket, the objects are named doc/doc/thefile2.txt, the file.txt,the file2.txt, and doc/thefile.txt.

– Spaces are not allowed in each line in the URL list file. Spaces may cause migrationfailures because they may be mistakenly identified as object names.

The task group is displayed in the migration task group list.

4.2 What Can I Do If Not All the Objects Specified inthe Object List Are Migrated?

SymptomThe object list used for querying objects on Kingsoft Cloud contains garbledcharacters. As a result, some objects specified in the object list failed to bemigrated.

Possible CausesKingsoft Cloud SDKs uses GBK encoding, while RDA uses UTF-8 encoding. Thisleads in garbled parameters for querying source objects.

Solution

Step 1 Configure the following environment variable.

Name: JAVA_TOOL_OPTIONS

Value: -Dfile.encoding=UTF-8

Step 2 Restart RDA.
