Hey everyone, I'm trying to migrate all of our SQL services to a new network infrastructure, including new vlans and IP addresses. I have a 2012R2 Windows Active/Passive cluster with SQL 2014 Standard. The cluster holds 5 SQL instances, all of which need to be re-IP'd and migrated.
I'm trying to do this in phases and with as little impact as possible. One of the methods I was testing out was to build 2 new nodes, so C and D nodes, add them into the cluster, install SQL, move services to the new nodes, and then slide out the old A and B nodes.
Technically, this works, I can set up the stretch cluster and the C/D nodes are added in fine. However, I get the error when installing SQL on node C that SQL standard can only have 2 nodes at once. Is there any way around this? I've tried removing the B node from the possible cluster owners and install SQL on the C node, but same error. Eventually, I'll come back to having 2 nodes in the cluster, I just need to add in a 3rd node temporarily so I can remove the others.
I'm already thinking of a plan B to do this migration, but I wanted to throw this out there in case anyone had any thoughts around this.
Thanks in advance! Appreciate the help..
