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