Hi

We are in the middle of a large re-IP project for all of our servers, which include several 2008R2 SQL two node clusters.  I'm wondering if there is a best practice for changing the IP addresses?

Our thoughts so far with changing the IP's in order:

passive node
active node
Windows cluster IP
SQL IP
DTC

Any recommendations?

Your plan looks OK.
Are IPs in the same subnet? Do you use separate heartbeats?

If you don't use separate HB interfaces, then make sure that Subnets successfully changed in Networks tab of Failover Cluster msc.

yes, the new IP's are all in the same subnet, but different from the current subnet.  We don't use heartbeat interfaces on any of our SQL clusters (don't ask).

Going forward we will have a few SQL 2005 and maybe one SQL 2000 cluster.  Any gotcha's with those?

It all looks good, just change the IPs and make sure that DNS gets updated.
I'd recommend ipconfig /flushdns on each node after change for safety.
