Have you converter from Polyserve to Windows 2008 R2 clusters yet? If so how did it go. Have you heard anything more about the end of life for Polyserve? We will be moving our database off of Polyserve to Windows 2008 R2 servers running on vMware. Any lessons learned from your swith over would be appriecated.
I feel your pain with this. We've not quite finished the migrations, but we're very close.
Only advice really is to be thorough with the testing of your new windows cluster and work through as many possible disaster scenarios as you can. This was something that I should have spent more time on when implementing Polyserve. The other piece of advice is to work through any migrations in a test environment first, that way you can find any connection strings / port no.s that need to be changed.. all very standard!
A major plus point of Windows clustering for me is, that if I find an error I can google it and get some good answers! :-)
