Hello All,
I have a 6 node GEO cluster, 4 nodes in primary site + 2 nodes in secondary site. In the primary node 03 and 04 has 2 pair of SQL instances default + named.
I am planning to move the named SQL pair from WSFC 2008 + SQL2012 TO WSFC 2012 + SQL2014. It has only one AG group with 4 TB of DBs.
Do you guys have any experience and options for this migration. I am planning to go with backup/restore. Let me share yours inputs.
1. Backup/restore 2. cross cluster migration 3.Detach/attach 4. SAN migration
Thanks!
