I have two servers with SQL 2005 running as separate instances. I now want to install a cluster over the two boxes with SQL Server 2008R2 while keeping the 2005 instances running for a while. The databases will then be migrated over from the 2005 instances
to the cluster for testing. After a test period, the 2005 instances will have a final migration and be decommissioned.
So for server001, server002 and SQL Cluster name SQLCLU001, I should be able to reference them all on the network individually after installation and the individual instances will continue to run on the local disk until decommissioned IIRC.
From what i've done before, I think this should be fine and shouldn't throw any issues but I wanted to check that there weren't any obvious blockers to this. Licenses are all ok, servers are fast enough to cope with the new configuration. It's just the process
I wanted to check out as i've not done an upgrade in quite this way before
