Hello, we currently have DMX4s and will upgrade to VMAX next year.  We have IBM mainframe, Unisys mainframe, AIX, Windows, VMware etc connected to the Symm arrays.  We are using old style TimeFinder (symmir) with BCVs on our IBM mainframes.

Soon we will be implementing replication on our Unisys mainframe.  It seems the new direction is towards symclone with standard volumes and away from good old symmir and BCVs.  Is this correct?  As we work on new projects for replication should we use symclone or symmir?  Is there a stated direction from EMC?  It seems like symclone has a definte advantage in that it does not need to use a mirror position.
