METHOD 1 :
Prepping for Workload Migration to the Cloud Moving to the cloud? You have choices to make.
Peak 10 offers migration services that can help you and your workloads get there safely, efficiently and cost effectively.
5 often-used migration methods
Here are
along with the advantages of each and related considerations to help with pre-trip planning.
➡

➡
MANUAL DATA migration to new OS and application environments
OFFLINE MEDIA transfer involving the shipment of portable media
INTERNET TRANSFER of virtual disk images
SOFTWARE agent-based data replication to new OS and application environments
FULL SERVER failover into the cloud using software agents
Let’s explore each one.
METHOD 1 :METHOD 1 :Manual Data Migration from Old to NewManual Data Migration from Old to New
555
Here’s how:
Get access to the new environment from your CSP.
Copy over your data and configurations via the Internet.
Make sure everything migrates to the new environment, no unknown dependencies surface, and the application isn’t attempting to communicate with something that’s not there.

Why manual data migration is good:
Distance is not an issue.
It is very cost effective.
Tools are usually free (e.g. mysqldump and Robocopy).
It offers the ability to dry-run transfer with no production impact.
➡
➡
➡
➡
77
Things to consider:
It involves in-flight data; always encrypt.
Best for simple applications.
Maintenance window varies with data size.
Internet connections can be a bottleneck.
Not good for short Recovery Point
Objectives (RPO).

METHOD 2:Offline media transfer by shipping portable media
999
Here’s how:
Perform the conversion and copy to drive.
Ship via a reliable carrier. Import the virtual
images and test.
Take care of DNS, VPN, certifications and
other patch items associated with the move.
➡

➡
101010
Why offline media transfer is good:
It’s good for transferring native format
systems (VMware source to VMware
provider) or converting systems to CSP’s
format (Hyper-V source to VMware provider).
Tools are typically free.
It doesn’t require media and courier
service costs.
➡
➡
➡
111111
Things to consider:
Data is handled by a third-party; always encrypt.
Lack of a USB increases time.
The production system data is lost throughout
the copy/conversion process.
Service is unavailable as long as maintenance
window remains open.
There is a long maintenance window.

METHOD 3:Internet transfer of virtual disk images
131313
Here’s how:
Upload workloads in native format or CSP’s format to a SFTP server or similar system.
The provider imports the virtual images to its cloud via the Internet.
➡
➡
141414
Why internet transfer is good:
Transferring in native format saves from having to rebuild application environment.
It’s good over long distances.
There is negligible latency with distance and network.
Conversion tools are typically free.
➡

151515
Things to consider:
You must take into account internet bandwidth size and cost at source and at target.
It may require software but at a minimal cost.
You need to protect in-flight data over unsecured networks.
A full data copy must be complete before services can be started on the new environment.
It’s good for smaller data sizes and VMs.
There is a long maintenance window.

METHOD 4:Software agent-based data replication
17
Here’s how:
Install replication software on the old server and the new destination server.
When the new server catches up with the old server, stop replication and test the new servers.
Restart synchronization until the new server catches up again with the old server.
Test and failover.
➡
➡
➡
➡
18
Why data replication is good:
It is good over long distances.
It allows migration heterogeneous environments (e.g. Xen to VMware or Amazon to Peak 10).
It replicates over time without impacting production systems.
It’s good for large data sets.
There is a short maintenance window; quick failover.
➡
➡
➡
➡
➡
19
Things to consider:
There is a cost for Internet bandwidth both
at source and at target, replication software
and for more experienced labor.
It can be complex when many servers
are involved.
Unexpectedly large changes to source-system
data effectively restarts the process.
➡
➡
➡
METHOD 5:Full server failover using software agents
212121
Here’s how:
Install the software on the old server and replicate the entire source system to a shell VM, agent to agent or to an aggregated target such as a VM appliance.
When the new server catches up with the old server, stop replication and test the new servers.
Restart synchronization until the new server catches up again with the old server.
Test and failover.

Why full server failover is good:The target server is a complete duplicate of the source server; no rebuilding, reconfiguring or dependencies.
It allows migration heterogeneous environments, such as Xen to VMware or Amazon to Peak 10.
It replciates over time without impacting production systems.
It’s good for large numbers of servers; method scales well.
There is a short maintenance window; quick failover.

232323
Things to consider:
It is the most costly of the five methods.
You may need temporary resources at the
CSP to facilitate the migration.
There is the cost of Internet bandwidth both
at source and at target, and for replication
software and more experienced labor.
Unexpectedly large changes to source-system
data effectively restarts the process.
