I have the task of restructing our SQL nodes which are currently in a cluster of three servers. These would be configured in a stand-a-lone configuration. Currently one server holds an instance, and the other two, two instances respectively. I do have additional servers, so building new servers for accomplish this task is an option if needed.
I am looking for the best method of removing the breaking up the cluster and redistributing the SQL instances, with the most minimal downtime, as these are all critical systems. One instance is required to be installed as the first instance, as it is now.
I am wondering if I can evit the nodes and destroy the cluster, leaving my SQL instances intack or is it more complicated than that. Also if you could point me towards any best practices references that are good, I would appreciate it.
