Migrate Exchange 2007 SP3 RU13 (CCR) to Exchange 2013

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.

There should be no different if your mailbox role in 2007 is using CCR. Regardless you are moving the mailbox to a different database so the mailbox will be removed from the active and passive database server on Exchange 2007.

Aside from that there should be no differences.

Use Exchange deployment assistant tool from MS.

Will - Ok so where I am confused is this....

CCR Windows Cluster is called Email-Cluster with ip and the Cluster group is email1

Right now all of our Outlook clients are setup for to connect to the cluster group : email1.  I don't want to change servers and then have to re-setup everyone's Outlook client to connect to a different server?

Amit - I looked through that but didn't ask me anything specific to CCR and didn't seem to address it.

You are planning on going from Exchange 2007 to 2013, correct? When you install your Exchange 2013 server you will need to move the mailboxes to the new 2013 server. You will not have to "re-configure" users Outlook clients because they will use Autodiscover to find the Mailbox Database Server where their mailbox is located. All they should have to do is close Outlook and re-open it.

That's it.

You will not see specific scenarios regarding CCR becuase it does not matter. As i have stated already.

CCR is 2007 feature related to mailbox DB HA. It doesn't have anything to do with migration. It will be running as it is during migration. You just need to move mailboxes to 2013. Later during decom of 2007, you need to break the CCR and then decom the server.

Thanks Will...I don't know why I wasn't thinking about autodoscover....duh. I will install/setup the new exchange servers (mailbox role first) and move a test account over to ensure autodiscover is setup and working properly.

Thanks again Will!
