That is a possibility ... I thought FLARs did not work with ZFS yet, however.
This is very brute-force however and not easy and elegant like doing a cold
migration using vdisk files!

They are both the same hardware ... T5120's with the same firmware/OBP/LDom
software on each ...
In the case of the ones we have previously migrated successfully via copying
over the vdisk files the Control LDoms were running the same OS ...
