MRS Migration From Exchange 2013 to Exchange 2010

I'm trying to do a remote mailbox move, from an Exchange 2013 SP1 org to an Exchange 2010 SP3 Update Rollup 7 one. However I'm presented with the error message The remote server doesn't support client 'Exch1.fabrikam.com' version (14.3.178.0 caps:05FEFF). Missing functionality: 'TenantHint'. Exch1.fabrikam.com is the name of the CAS server in the Exchange 2010 org.

The cmdlet being used is: New-MoveRequest -Identity frank -Remote -RemoteCredential $RemoteCredentials -RemoteGlobalCatalog dc1.contoso.com -TargetDatabase Global1 -TargetDeliveryDomain fabrikam.com -Verbose -RemoteHostName Exch1.contoso.com.

There is also a similar thread here, but it never got solved.

Although I'm finding it hard to believe - is this something that's not officially supported ?

This is interesting; I agree its a very quiet issue. Have you tried moving from both orgs? What if you target a -MRSServer in the other org when moving from the OTHER org? I guess the other option is to export-mailbox to a .pst and import-pst when you create a new account on 2013 :-/. I know its not an answer but its a workaround.
