The only things not in the database that is can think of are uploads, which the docs you linked describe how to back up before an upgrade.
Upgrading from 0.6 to 0.7
I want to migrate and run a forum on 0.7 but the import plugin actually only works on 0.6 ( on 0.7 gets stuck)
so, any way to update form 0.6 to 0.7 with same database and without losing posts and users?
The import plugin is one time use. So if you've already imported your db, I think you can get rid of the plugin and update your forum.
@a_5mith yes. Of course is one te use. Question is how i change to dev branch. With git pull it keeps me on 0.6
You would have to shut from stable to master. Master isn't advised to be used in production, but for testing is fine.
To change branches you would type
git checkout master
You may need to disable incompatible plugins if their are any.
