    The two methods that come to mind are:

    1. Adding the new control enclosure to the existing system, i.e. as a cluster, migrating or mirroring the vdisks to new storage pool(s) using disks from that new control enclosure (+expansions, if any), then moving the vdisk and host access into the new I/O group.  Once you've done this for all volumes then the original control enclosure can be removed from the configuration.

    2. Create a new system on the new control enclosure, then partner the two systems for remote copy, e.g. metro mirror, then use that to sync the data across to the new system before switching over the hosts to the new box.

     

    You definitely definitely do NOT want to use the svcconfig backup/restore functions for this activity.  That isn't what it is intended for.
