Yesterday I used the Virtual Media Library to do a migration of an LPAR from AIX 5.3 TL 11 to AIX 6.1. The migration took under 25 minutes. This included:
- the migration itself (15 minutes)
- a reboot,
- installation of the service pack
- another reboot.
I then installed the latest service pack, once again via the VM Library. This took just over 2 minutes. I had downloaded the service pack from the IBM Support Portal.
Fast and painless migrations
All up, the migration was about 25 minutes, including rebooting time. Of course, this doesn't include the preparation time downloading the software or time to take a backup.
This is just a few minutes faster than the migration to AIX 7.1 which I did on a different LPAR last week, but both of them were really very fast and painless. That's how it should be.
