Migrating Exchange 2007 to Exchange 2013: Outlook anywhere Question?

Hi All,

I am working on a Migration project Ex2k7 to Ex2k13.

Both are in Different AD Site.

Ex2k7 Outlook anywhere is not enabled. Is it mandatory to Enable Outlook anywhere in Exchange 2007 before starting the migration?  Please confirm.. Since Exchange 2013 internal and External users are connects via Outlook anywhere so i am not sure at this point.

I have gone trough few articles it same we must enable Outlook Anywhere in Legacy server.

Thanks,

Balgates
