Extended modules migrations

[Yasaie]

Hi everyone,

I have a custom module in odoo 13.0 that now become 2 separate modules in 14.0 and I need to migrate related data across both modules.
There is a merged_modules in apriori to get analysis and data but not in reverse for extended_modules.
Do you have any ideas what should I do in this kind of situations?
Would you please reference me to an example module?

Just install the new module in the target database.

Example: This one didn't exist in v11. https://github.com/OCA/social/tree/12.0/mail_attach_existing_attachment_account

I had a module in 13.0 for example module_foo that now become module_foo and module_bar in 14.0.
I need to move some tables, fields and xmls that transferred and some changed from module_foo to module_bar.
How do I install module_bar while upgrading module_foo so I don't have any data loss?

As said, just install module_bar when the upgrade is completed. You won't lose anything.
