Hi Mark,   If the two existing unts are in individual groups, you can't merge them and retain the data.  Also this is a mix of GbE and 10GbE?   That makes it a little trickier.   You can add a new unconfigurated unit to an existing group presuming the firmware of the systems are compatible.    So for at least one of the old members you will either have to replicate the data to the 6510 or use host based copies, e.g. Storage vMotion for ESXi, or robocopy, richcopy for Windows, rsync for Linux, etc...  Regards, 
Hello, We have two existing EQL units that were never actually placed into a group. They have successfully done their thing for the past five years or so, but now it's time for an upgrade. I've got a couple PS6510Es ready to assemble in the data center. The first will be for production, the second will be for replication and snapshots only (eventually headed off-site). I have a simple plan for getting all data migrated from the old EQLs to the new: I am going to join the existing EQLs (PS4000 and PS6010 running V7.0.9) to a group and then join the new EQLs once they have been built. Since it seems too easy, I am concerned about the Group building process. I just cannot locate a case or write-up where someone has pulled two production EQLs into a brand new group (where they are the only members). I'm probably missing something, so if there are any pitfalls or gotcha's that I'm missing. Thanks in advance, Mark 
Creating a group for existing PS4000 and PS6010 - Just checking.
