Exchange 2007 transition to 2010 - CAS server issue
Posted on 2011-03-12
Exchange1 - 2007 sp1 with hub, mailbox roles
ExchangeCAS - 2007 sp1 with CAS role
We are looking to transition to exchange 2010 but I have some issues. I know I need to upgrade my Exchange to minimum sp2 prior to installing 2010 but somewhere along the line the ExchangeCAS server has been running out of disk space, and a disk cleanup has been performed which has got rid of the original exchange installation files, so I am unable to upgrade as it fails on uninstalling the original installation.
So I am wanting to know what my best option is. My thoughts below but apologies for the vagueness - I am trying to give you an idea of what I am thinking to do but feel free to tell me if I am on the wrong track.
Build a new Exchange 2010 client access server and use that. I use a san certificate from Digicert which would allow me to rekey it with the new server name.
Would the new cas server work with the main Exchange server 2007 it being only sp1 or would I have to upgrade that prior to installing the 2010 cas.
Would I have to do anything to point my Outlook clients to the new cas server.
If I cannot uninstall the exchange components from the old CAS server is there a guide to remove it manually from the exchange/ad organisation.
Would my outlook clients automatically pick up the new cas server
