Migrating to AIX 7.1 with nimadm.
Last year I wrote an article on using nimadm
to migrate to AIX 6.1 . The procedures outlined how to migrate a live system with nimadm and a spare disk. Another method that I have found to be extremely useful is
the migration of mksysb images from one version of AIX to another using (you
guessed it) nimadm . In the following example I migrated an AIX 6.1 mksysb image
to AIX 7.1 and then used that image to install a new LPAR via NIM. The source LPAR was running AIX 6.1 TL6 SP3. I took a mksysb
of this system to my NIM master. # oslevel -s... [More]

AIX multibos mksysb migration
I’ve
written about multibos before, here and here . But recently I
started experimenting with multibos mksysb migration. A customer asked me how
this worked and apart from a high-level view I wasn’t able to provide any real
world experience, so I thought I’d give it a try. What follows is just a ‘brain
dump’ from my quick test. First of all
this isn’t really a migration. It just simply populates a second instance of
AIX with a higher-version. It doesn’t really migrate (or merge) your existing
configuration into the second instance. So... [More]
