Why does a database migration to Symfony2 using DoctrineMigration change something that hasn't changed?

Question

symfony

Hello.
I ran into a problem, found that Symfony2 has a convenient bundle for migrating the DoctrineMigrationBundle database, but for some reason it nulls out all the comments and drops the column with all the contents when it is renamed, which is not entirely correct, plus for some reason it drops and re-does creates all keys. How to do the right migration of the database to production, do you really have to write your own solution?

Answer 1

Can it is necessary to write normally migrations? doctrine:migration:diff gives you a framework to work with. It needs to be checked and corrected for your needs.
