A.6 Migrating Resources to Another Cluster
IMPORTANT: If you are migrating a pool to a cluster in another tree and you want to maintain that
pool's volume trustee assignments, you must migrate the pool to a server with an eDirectory replica.
The replica must be at least read-only and must contain all users. After migrating the pool to a server
with an eDirectory replica, enter the following console command on that server for each volume in
the pool:
NSS/ResetObjectIDStore=volumename
This command updates all volume trustee assignments and should be run at night, on a weekend, or
during a period of low network utilization. Trustee assignments become effective immediately, but
might take a few hours to display correctly in management utilities.
If you migrate the pool to a server in another tree without an eDirectory replica, you must, within 90
days, migrate that pool to a server with an eDirectory replica and then run the command for each
volume.
