Merging drives under VAX/VMS V5.5?

I'm looking to merge a couple of RZ29's down to a single RZ28 (everything will fit). Does anyone have any advice? Basically I'm trying to downgrade a VAXstation 4000/vlc from a BA350 with 3 7200RPM RZ29's (user disk is a shadowset) to a single 5400RPM RZ28 that I'll put in an external enclosure after pulling it from the SBB brick. The BA350 and 3 RZ29's generate a *lot* of heat. I've done plenty of migrations to larger disks using BACKUP/IMAGE, but have never tried to combine separate disks onto a single disk. I would think that the following would work, but it doesn't preserve the ownership of the directories and files (at least under 5.5). BACKUP DSA1:[GU*...]*.*;* [...]/VERIFY/LIST Zane -- | Zane H.
