Hi Frank,
I took this excerpt from the the AIX admin tips section on IBM's support site, for AIX 4.X migrations:
Space requirements for the migration depend on the amount of data stored in the root volume group. For most situations, the following space requirements suffice:
/tmp - 15MB free space / - 10MB free space 80MB of unallocated physical partitions in the rootvg
So using the above guidelines, you should be ok, but you are
cutting it mighty close.
As for reducing the /usr filesystem I think the only way you
can do that is to edit your image.data file to make /usr smaller
and then take a mksysb and use it to reinstall the node, thus
shrinking the /usr during the reinstall. This is just of the top
of my head, as I have never done this.

Hi *,
I have 2 questions:
- Have somebody any information how much increase the rootvg when I migrate
from 4.3.3 to 5.2?
- How to restore /usr ?
I think that I need for the migration from AIX 4.3.3 to AIX 5.2 more space
in my rootvg (SP - silver wide node). In the moment I have only 96 MB free
in the rootvg. But when I check the filesystems, I observe that /usr have
933MB free.
But what is the way to reduce /usr???? I think that 'delete filesystem' and
'restore' with TSM in a smaller lv isn't possible by /usr
What can I do?
Have somebody any information how much increase the rootvg when I migrate
from 4.3.3 to 5.2?
Best regards,
Frank Mueller
