Currently have a single stand-alone search head.  We did NOT install it as a single-member SHCluster.  At the time I didn't know that could be done.  We have 2 more servers coming so that we can create a 3 member search head cluster.  I've been through a ton of docs but can't figure out the best way to accomplish this task.  Is there a way to take the existing stand-alone search head and turn it into a single member SHCluster?  So that I can easily then add the other 2 servers into the cluster?  I can't find a doc for that.  Or do I have to take 1 or the 2 new servers set it up as a single member cluster, then migrate all the app and settings from the existing stand alone search head  to the new single member cluster server and then add the other 2 servers? Appreciate in any insight anyone can give me.   Thanks ... View more
