I am performing an exchange 2007 SP3 Rollup 10 to Exchange 2013 CU3 migration. Followed all the steps from various guides, mailboxes have move over successfully and everything is running smoothly for Outlook clients, OWA and mobile access. I'm getting to the part in the documentation that states I need to migrate public folders now. My question is, there are no public folders, the company doesn't use them, there are none configured, so do I need to follow all the steps to migrate something that isn't there ? I'm guessing there is still type of exchange system public folders that I don't see that are required to be moved to new exchange server but that's what I'm trying to figure out.
