Currently I have a 2 Node Active/Passive Windows Server 2003 X64 with SQL 2005 Cluster
I am bringing in two new servers and need to migrate the sql server and also upgrade OS and SQL both to 2008 R2.
What is the easiest and safest way to perform? What is the ideal sequence of OS and SQL installs and what is the best method of migrating the 2005 SQL dbs to the new server?
I understand different scenarios would have different considerations, I am just looking for a general high level outline of the steps for a starting point.
