Question : Mailbox move

Background: We have a W2K server running Exchange 2000 which is a DC.  We also have a W2K3 server which is operating as a DC.  Installed W2K8 server w/Exchange 2007 as a member server.  Transferred the FSMO roles to the 2K3 server and am trying to migrate the mailboxes and then decommision the 2000 server.
When attempting to move mailboxes receive the following message:   ErrorCode="-2147467259">One or more of the following mailbox policy settings failed to validate: Unified Messaging, Messaging Records Management Content, and Exchange ActiveSync. To remove the policies, specify the -IgnorePolicyMatch parameter. The domain controller 'cismail.cis.sls.lib.us' is running operating system version 5.0 (2195) Service Pack 4. The minimum version required is 5.2 (3790) Service Pack 1.
 

Answer : Mailbox move

GUI will not give you optionto specify -ignorepolicymatch parameter. Try to move mailbox from powershell using this syntax

Move-mailbox -Identity "mailbox" -TargetDatabase "YourTargetDatabase"  -IgnorePolicyMatch:$false

Powershell is much more powerful and responsive believe me:)
