Renaming a Cluster Resource

We recently moved the server room from in house to a data center. While power, air, security and seismic capabilities were good reasons, it had to happen because the entire company is moving out of the building! Anyway, while the VMs were not a big deal – other than bandwidth – the physical sql servers required attention beforehand for installation, configuration and mirroring set up to keep the downtime to a minimum. One of the tasks on cut-over night was renaming 2 of the sql cluster instances back to what the applications expect. It turned out to be a simple task, less steps than renaming a standalone. This msdn article has all you need. I was surprised the local server in sysservers was updated as part of the process.
