My layout is as follows:
I have a physical server that has 5 VMs - Host is Windows 2012 R2
1-SQL Server 2012
I also have another Physical Server that has a replica of all of these VMs. Host is Windows 2012 R2
The replication is working fine.
I am running out of disk space on both physical servers and adding disk space need to turn off the servers which I cannot afford.
I got a new server (rented one for 1 week) with enough space.. and I did set it up as extended replicas from Server2.
and the extended replication is working fine.
Now I am about to take the step of "fail over" from the 3rd server (where I have the extended replication.)
But I have never done this and I am quite unsure about the steps...
Can someone please help me on how to do this "the safest" possible way ?
I was thinking of turning off my primary server (Host) and THEN fail over from the 3rd Server. THEN turn off the second server once all is ok.
If there is anything wrong, I can then turn back ON the primary.
Is this the right way of doing things ?
