Migration from 1.0X to 1.5X

Why Migrate ?

Where to Start

What all do you need ?

How it works

Getting Started

ETL Plugins & Third Party extensions

Putting all the things together

Potential Issues

Why Should I Migrate ?

1.0 End of Life

No new 1.0 Extensions being developed

1.0X Extensions will be reoved from the extensions directory port July

No more security Updates

1.5.X has many improvements over 1.0.X ..

Why Should I Migrate ?

1.5.X has an MVC Architechture

Adds ability of layout overrides without hacks

Access to host of new feature & UI updates available in 1.5

Better Plugin Call support.

Access future release which include security releases.

Better positioned for future migrations.

Where to Start

Pre Migration Analysis - Extensions

Pre Migration Analysis Template
- Can this one run in legacy mode ?
- Does your template provider provide a 1.5 version ?
- Can your template developer convert it to 1.5 for you ?

MYSQL table structure analysis ( 1.0 VS 1.5 ) for extensions without ETL plugins.

What All do i need - 1 ?

A. The Migrator Component

The migrator component basically converts your Joomla 1.0 DB to a 1.5 compaible format.

It achieves this using a number of 'ETL' plugins

The core component comes with all the plugins you need to migrate the core Joomla content.

The migrator can be extended to migrate other components as well using ETL plugins.

How the migration works

Extract, Transform, Load

1.0X DatabaseTransformEg converting old mosimage tags to img

1.5.X Compatible DataExtraction

What All do i need - 2 ?

B. The ETL Plugins

Get all the ETL plugins that are available for 3rd party extensions.

C. A Copy of 1.5X ready for install

Get the latest copy of Joomla 1.5 X ready to be installed in a subfolder of the site.

What All do i need - 3 ?

D. Third Party Extensions

The 3rd party extensions that you need Legacy or Natively compatible with 1.5

E. DB access to both 1.0 & proposed 1.5

F. A Large cup of coffee !

Let's Start !

Install com_migrator on your Joomla 1.0X site.

Create Migration File Add 3rd Party PluginsI prefer it via ftp its faster

Extending the Migrator

You can extend the migrator component using ETL plugins.

Create the Migration File

Once all the ETL plugins are in place, we are ready to export our migration file.

Go ahead & create your migration file. You can chose to exclude any extensions from the migration when you do this.

Any extensions not having ETLs will need to be migrated later

Getting it all in 1.5

Once done, start the installation of Joomla in a Subfolder on your site. Complete the installation upto the main screen below as you would normally.

Getting it all in 1.5

Now instead of clicking on 'Install Sample Data' select Load Migration Script

Make sure you check 'This is a Joomla 1.0 migration script'

Getting it all in 1.5

Click on Upload & Execute. Once the migration is complete you should get a message as below.

Click on next & complete the installation as usual.

Are We all Done ? - Not Quite

Site Name is not migrated so the one you specify during installation is used.

We still need to install the third party components like CB , VM, Fireboard etc.

We still have to migrate extensions that did not have ETL plugins

The Template still needs to be applied.

Modules & Templates assignment to menus & full testing still needs to be done.

Install all 3rd Party extensions

The next step is to install all 3rd party extensions. The ones we migrated using ETLs as well as the ones that we need to migrate manually.

Once installed if the migration went ok the extensions that had 3rd party extensions should be migrated.

Note that you may have to enable the legacy plugin if any of your extensions is not 1.5 native.

Migrating Extensions not having ETL plugins

There are lots of ways to do this

You could write your own ETL plugin & share it with the community.

Write a custom script to migrate the database tables

Do it via PHPMYADMIN

Migration using PHPMyadmin

Get Table Comparison from Pre Migration analysis.

Take a backup of your 1.0 Database & dump it on a local/test server.

Get the tables of the component in the backup of your 1.0 DB in the same structure as your 1.5 DB

Export data from 1.0 & import into 1.5 using PHPMYADMIN.

What can have changed ?

New columns may have been to the 1.5 structure.

Table field names may have changed.

Columns may have been removed etc.

As long as you make sure that the changes you make are logical & make sense with respect to the working of the extension you should be OK.

Another Approach

If you cannot install a new Joomla or its already installed you can use the Migration Assistant

Note that this will completely wipe your current data from the 1.5 site & replace it with the migrated Data.

The Template

If you wish to maintain the template you had on 1.0, you can enable legacy mode in your new 1.5 site & check if the template works ok. If so you are done.

If not or if you wish to use Joomla 1.5's new abilities get the template properly coded for 1.5 & then use it.

OR take this opportunity to give your site a fresh new look with a nice 1.5 native template !

Putting all the pieces together.

Once the template is installed & applied, make sure your module assignments are as they should be.

If you are using multiple templates, also check the template assignments.

Make sure all links are working ok.

The Backlink Plugin redirects old style URLs and document links to the correct Joomla 1.5 targets. So turn it on.

Test Test & Test Again

Finally with everything in place i neednt tell you but test , test & test again.

Make sure all extensions , components, plugins and modules are working ok.

Typical things you might miss are content plugins which might leave ugly {somethings} lying around in your content.

Potential Issues & Solutions

404 Errors Esp when using 3rd Party SEF Extensions

--- Try to match the urls so that they perfectly match older urls

--- If not possible export all old urls & add them as 301 redirects

New Users/ Forum posts/ Articles etc might have been added while you were migrating the site. --- get that data before you go live.

GO LIVE !

Once you have made sure that everything is working nicely you are ready to take the site live !

Make the 1.0 site offline & move it to a subfolder. Also make the 1.5 site offline.

Move the 1.5 site to the root folder & make the necessary changes in the config file & then make it LIVE !

Thank you !
