Hello,   There's no way currently to merge groups together and leave the data intact.  If you have enough room, you can replicated from one array to another.  Promote the volumes and re-login.  Then reset that array, add it to that group and repeat the process for the third array.    Sometimes its easier to move the data at the host level, get the most critical volumes over and backup the rest if you don't have enough free space to replicate them.    Regards, 
Hi there, We've got three arrays, each of which is configured into a standalone group consisting of one member.  This was done for historical reasons which aren't really relevant anymore.  Assuming I've got them all revved to the same firmware, what will it look like to merge the three groups into one?  Is there a way to do this while keeping volumes intact or am I in a house of pain here?
