So I have migrated my groupware platform from Exch2010sp1 to Google Apps (sorry, MS, but if you gave 365 away for free to 501c3's I would have considered it). I am using Google's Google Apps Directory Sync (GADS)to populate GApps, and intend to maintain my AD infrastructure and add users that way via the Exchange Admin tools. However, I don't need the Hub/Client Access/Mailbox DB role installed anymore.
Everything that I have found in looking to date is for the reverse (e.g. people with problems where they have managed to remove the Mailbox DB role but they still have the Exch AD attributes) of what I need. But in looking at EMC and the PS Remove-Mailbox-Database cmd, everything seems to want to remove the Exch AD attributes. And, of course, just disconnecting the Mailbox DBs isn't feasible, as the DB still contains all my user mailboxes from pre-migration.
Is this even possible? Would it be something I could do via ADSIEdit? I'm certainly willing to go there, but probably not without some good expert guidance, as I feel like I could hose my schema pretty good by trying that on my own.
Much thanks in advance for any assistance.
