Migrations

Do we need to create forms again while migrating forms from v6 to v7? or is there any other way of migrating?

Hello,
I have to change my Bonita from one server to another (without changing version)

I think it's not enought to just export and import database because there are data contains into the webapp folder. Is there a complete documentation about that?

Thanks in advanced

PS : For information, I use Bonita 6.5 Community

How is the evolution of BDM handled? Adding or removing columns (fields), renaming, and other operations. I don't see any documentation on this. Is this done outside of Bonita by accessing the DB directly?
