Hello,

I'm new to odoo and I'm trying to migrate a module built for v12 to v13 but I'm having a hard time finding the correct models and changes I need to apply because there is not a clear path on the changes on a Model. I tried to look into the changelog for odoo v13 but could not find technical information like rename of fields or rename of models.

For example, the field  "account.invoice.journal_id.purchase_type" I know that "account.invoice" is now called "account.move" but I cannot get any further. 
 
Anybody knows if such documentation exists.

Thanks,
