I want to have failover disaster recovery by adding a new 2012r2 server and using hyper-v replication to my current/old 2008r2 server.
I have got the new server up and running and now have to prepare the current server for the transition. I have a lot more known unknowns and unknown unknowns than I have known knowns. So, I keep coming here with vague questions to get best practices and how to get from a to z type answers.
As to my 5 year old current/old server running 2008r2 on a ESXi vm, my questions are:
Converting ESXi to Hyper-V machine with Microsoft Virtual Machine Converter- My data is taking up 60% of the disk space. Will the ESXi be removed or will I have space problems?
Does it matter if I upgrade the old server vm to 2012 first or the host first?
Would you leave the domain controller on the current server or is there any desirable use for the 2008 software and CALs on my old server?
As to 2012 CALs, is it right to place enough user CALs on the new server's vm for our staff and 2 CALs on the current server, one to connect to the new server and one for me to remote into the old server to monitor it from my workstation?
Based on my being a rookie amateur IT guy, what am I not thinking about with this transition from 1 to 2 servers that I should research so that a weekend is long enough for the transition to succeed?
