Hi Folks,
This is where I'm at: We have 2 Exchange 2010 servers (both multi role) and I was given 4 VM's for exchange 2013. I just completed installing Exchange on the four 2013 VM's (2 dedicated CAS and 2 dedicated MBX) and applied SP1. I documented all of the 2010 server config info (i.e. all the URL's for the namespaces, etc). We have a hardware NLB and a MacAfee host in the DMZ where all inbound/outbound email routes to check for AV/Spam. My question is, what are my next steps that take place so that I'm truly in co-existence mode? I'm assuming I want to make the 2013 servers primary now so that all mail routes to/from them and all client connections are made to them? Could someone point me in the right direction maybe to an article on what my next steps are? I want to get everything cut over while in co-existence so that I can start moving mailboxes. Thanks a lot !
