XF 2.2 Restoring for final import, what to do with XFMG?


Following the stickied "Importing" post here, I read the following:

Once you have done the import, if you wish to redo it, simply drop all of the tables from the XenForo database and import the clean master backup.
Then delete the attachments and avatar directories from the data directory and the attachments directory from the internal_data directory.

As part of my test import, I also ran an Photpost Pro import to XFMG. What do I delete to prep for my final migration, do I also delete the entire \data\xfmg folder? in addition to the above quoted steps?
