would like to inform that we have created 2 new modules related to data migration.
Now there are three modules in this group:
1. Module "server_migration" - main functionality;
2. Module "server_migration_config_data" - ready module mappings if you want to move data migration mappings created in one database to another. This is helpful if you want to reuse your work on several databases. For example, you may want to reuse migration mappings for the common modules such as Partners and several other base models.
3. Module "server_migration_demo_data" - holds demo data in order to better understand how to create model mappings. Model mappings in this module - Partners, Partner Address, Partner Categories, Banks, Users Tasks, Task Works, Projects.
All of them are available for download as zip'ed modules from our web-page as well as source and modules from launchpad.
I hope now it would be easier to understand how to create model mappings for data migration.
For reference there is brief step-by-step guide how migration could be performed.
