What is the best approach for migrating our 300 user Exchange 2003 organisation to Exchange 2013.? We use Enterprise vault v7.5 and the clients are Office 2003 on an XP desktop.
We are also planning to upgrade to Windows7 and Office 2013 this year so I am trying to understand the sequence. Should we just aim to upgrade to Exchange 2010 with Outlook 2010 instead?
Many thanks.
