Currently in the process of a public folder migration from 2007 to 2013. We have over 74,000 folders and about 8 million emails stored in our PF. So far about 2 million items have been copied over but I've generated a lot of transaction logs that will fill up my disk soon. Can I delete these transaction logs for the 2013 server? Or should I be backing up the 2013 database that contains the public folder mailboxes (no user mailboxes in the database with the pf mailboxes) during the migration? I'm sure this would get rid of the log files too. I'm still backing up the 2007 public folder database since it's still in production during this migration, which is why I'm wondering if I can just manually delete the log files for the database containing the 2013 pf mailboxes. Again, there are no other mailboxes in the 2013 database other than pf mailboxes.
