Hello sysadmins,
I must upgrade UNIX V3.2C to 4.0E. All Disks are mirrored under LSM, with
ADVFS on them.
As UNIX V4.0 and later needs another partition-layout, I would have to
unencapsulate and unmirror root and swap to change the partition-size.
How do I unmirror and unencapsulate root and swap. From what I know, there is
a difference in UNIX-versions before V4.0.
Here are the config-infos:

Is it correct to backup the sysdisk filesystems after unencpsulating and
unmirroring and then changing the partitions.
After restoring the data on the changed pertitions, how do I get to the
original
lsm-state of the sysdisk. (Advfs on lsm).
Any practical help is much apreciated.
Thanks in advance for helping.
Regards,
Gottfried
