I have migrated all user mailboxes and other Exchange services from 2010 to 2013 and am ready to uninstall Exchange 2010.
Public folders that were on the 2010 server are no longer used and all public folders (except Internet Newsgroups) have been deleted. There is currently NOT a public folder database on 2013, nor does there need to be. I understand and am comfortable with removing the 2010 Public Folder database in ADSIEDIT, similar to a Exchange 2003 to 2007/2010 migration.
When I go through the steps to make sure that I can delete the Public Folder Database, it shows my 2010 mailbox database, as well as my Exchange 2013 mailbox database using the PF Database on 2010 as the "Default Public Folder Database".
The question is, if I remove it via ADSIEDIT, will I be causing any problems with my 2013 Mailbox Database? I don't necessarily care about the 2010 Mailbox Database, as that's going to be removed in preparation to uninstall Exchange 2010.
