Migrate SQL 08 r2 cluster on win server 08 r2 cluster to SQL 14 on win Srv12 r2
I have a task of migrating a Multi-node SQL 08 r2 cluster on win server 08 r2 cluster to a Multi-node SQL 14 on win Srv12 r2 using the same storage.
Based on the research that I did so far, I concluded that I have to do the following:
1. Install the Windows Server 2012 R2 operating system, required server roles and features, and any services or applications that will run on the new failover cluster
2. Prepare storage for the new cluster
3. Create the new failover cluster and configure windows firewall
4. Migrate the cluster roles – Use the Copy Cluster Roles Wizard in Failover Cluster Manager to migrate the cluster roles to the new cluster.
5. Verify the migration.
However; based on https://technet.microsoft.com/en-us/library/dn530781.aspx SQL Cluster Role can't be migrated! I'm confused...
Can you please guide me through the process, and detailed step by step guides are very welcomed..
