Migrating root_domain from AdvFS to LSM disks

Sorry if this question sounds stupid, but I am not very familiar with Tru64...

We have a Tru64 system with V5.1A, the root_domain and usr_domain reside on an AvdFS disk, like:
root_domain#root 1048576 129854 911880 13% /
usr_domain#usr 4151048 365661 2627056 35% /usr
usr_domain#var 4151048 135763 2627056 5% /var

We want to migrate these domains to a LSM device using volmigrate on a new disk. Afterwards this new disk should by mirrored with the then free 'old' disk.

Are there any caveats to look for (except making a backup before), e.g. regarding booting etc...

Re: Migrating root_domain from AdvFS to LSM disks

To integrate root, usr and var of a single system into LSM you use the command volencap.
This encapsulates the system disk in-situ, ie on the disk itself.

Say your spare disk is dsk9 and the boot disk dsk0, then it goes as follows

volencap dsk0

## Reboot required

volrootmir -a dsk9
