NIMADM migration 5.3 to 7.1
I am attempting this for the first time having in the past used a DVD migrate. Unfortunately in this instance I do not have this luxury. The migration starts correctly and creates the alt_inst disk and them proceeds to create the filesystems and exports them. First failure was the filesystem /admin on the hd11admin logical volume did not exist on the client which caused a mount problem. However this will not exist as I believe the /admin filesystem appeared on 6.1.

I tried to get around this by creating a dummy LV on the 5.3 system which seemed to work! However it still fails with the following output:

Code:
 nimadm -d hdisk4 -c client1 -s AIX71_TL1spot -l AIX71_TL1 -Y

Just an idea: NIM can become pretty capricious if directories in NIMs working directories are being exported independently (even if only exported indirectly via exporting super-directories of them).

It might be a good idea to have a look in /etc/exports and clean up every entry regarding NIMs working directories or supersets of these prior to attempting any NIM operation.

This is - alas - a part not all too predictable about NIM.

I hope this helps.

Solved: NIMADM migration 5.3 to 7.1
The problem with a Google search is if you do not ask the question correctly you get spurious answers. I asked the correct question and found a link to an IBM known problem patch.

IBM IV13892: NIMADM FAILS TO SORT /ALT_INST FILESYS PROPERLY WHEN LANG=EN_GB - United States

I downloaded the patch, updated the LPP_SOURCE and SPOT, ran NIMADM again and it ran all the way to phase 12. The server came back correctly and reported the O/S as:
Code:
7100-00-03-1115

A success after a lot of searching!
