migrating a mailbox cross forest from exchange 2013 Sp1 to exchange 2010 SP2 Update rollup 8

I can migrate a mailbox fine from exchange 2010 sp2 update rollup 8 to exchange 2013 sp1 or Cu2.

I was testing today migrating cross forest from 2010 sp2 udpate rollup 8 back to exchange 2010 sp2 but I get the below error.  Is this even possible?  I cannot find any documentation on this scenario yet.

version (14.2.341.0 caps:05FEFF). Missing functionality: 'TenantHint'.

I think first thing you need to do it upgrade exchange 2010 to SP3 which is the min. supported version.

this is a correct assumption,

however to the OP...why are you trying to migrate backwards? that is/can be very bad with the way it writes values to the mailbox.

please confirm that you are trying to go backwards from 2013 to 2010

Its a just in case thing, this is not backwards as we migrated people from 2007 to 2013 and some back to 2007 temporarily when we encountered issues.....

I will load sp3 in my lab and test again.

thanks

for what type of issue you need to move mailboxes back to exchange 2007?

It was a couple instances where a specific app was not compatible with 2013 mailbox, since then we have resolved that.

Hi Steve,

I'm a little confused what you are saying. Here is my understanding:

When you migrate mailboxes from Exchange 2013 back to Exchange 2007, the above error occurs.

If I have misunderstood your concern, please let me know.

For migrating mailboxes back to Exchange 2007, there is a simple and straightforward method. Please use the New-MailboxExportRequest cmdlet to convert all mailboxes into pst files. And then use the Import-Mailbox cmdlet to import all pst files into Exchange 2007.

Hope it helps.

Best regards,

Did you ever got this resolved ? I'm hitting the same exact issue trying to go from Exchange 2013 SP1 to Exchange 2010 SP3 Update Rollup 7.

I did not, we proceeded and finished the migration.  If a migration fails the mailbox will not move.
