Thanks for that.

Don't know why I never thought of this before, coming from a VMS background, where clustering systems is an (almost) trivial task that we took for granted because, well, it was just what you did.

In particular, your thoughts about upgrading - this was exactly what we always did when upgrading systems, add the new hardware to the cluster, move the apps to the new system and move the old one to the 'development cluster'.

Moving in the small business circles that I have over the last 10 years, I'd all but forgotten about clustering, but you've given me a reason to start building up my skills in Windows clusters.
