I am currently running Exchange 2007 SP3 RU13 on Windows 2003 R2 SP2 machines and due to End of Support of Windows 2003 in July I want to migrate to Windows 2012 R2 servers and Exchange 2013.
Exchange 2007 is currently setup on 3 servers..
1. CCR (2 Mailbox Roles, active and passive)
2. Client/Hub (1 server hosting both roles)
I am able to find some migration information from Exchange 2007 to Exchange 2013 but I am finding very little about how to properly move from Exchange 2007 to Exchange 2013 when Exchange 2007 is setup as a CCR for the mailbox roles.
Any help/links/real world experience would be helpful.
