Hi Bharat

I would reccomend to use the odoo-ETL module to migrate the data, it allows you to generate a new database from scratch, with the same information, and you have whole control of what you do. You can download the module from:


For the process, a third database is used, where only the odoo-etl module is installed (the first db is the original one in V7, the second one is the destiny database in V8.

You can review the process here (spanish spoken, but you can watch the process:



Hope it helps!

First you must have Odoo enterprise contract to migrate your database to v8,

Or If you want to migrate by your own, you can use openupgrade, but it will be hard to do that.

 

For costume module, you need to change some code, to match the version 8 rule.

For the example:

Change

from osv import fields, osv

To

From openerp.osv import fields, orm

 

Another important one is to match the view structure to the version 8 view,

because some view structure is change or there’s no exist anymore(I don’t know why they remove some functionality.)

 

And you must test it to test the behavior of your module is worked as before or not.

 

And finally you must stop any development/ changing a lot of configuration when you are in migration process because it will delay you in migration process.

Normally if there’s  no custom module, the upgrade process is very fast just less than 1 week.

But if we have custom module, the migration process will be more than 1 month,

And if we do a development/changing a lot of configuration and implemented it to the database, they will ask us to wait 1 month again to redo the process of migration.

 

This is based from our experience.

 

 

Thank You.
