AIX migration 6.1 to 7.1

Alternate disks migration is one way to migrate the OS from 6.1 to 7.1, and to implement this method we needs an empty disks, Is there a way to do this without an empty disk

what are the ways to migrate if I am only limited to one single disks for ROOTVG

Alternate disk migration definitely requires an empty hdisk, there's no way around that.

AIX migrations are not supported with Multibos (two or more BOS images in one rootvg) either.

You can of course perform an offline migration, and I'm afraid that this is your only option.

Please be aware that after performing such a migration you cannot go back to the old version without restoring a previously taken mksysb.

An offline migration is done by booting from the 7.1 installation medium. Once the installer is up select "Migration Installation" and follow the displayed instructions.

Never forget to create (and verify) an mksysb image on bootable media (DVD/Tape/NIM) before attempting a migration!
