This process worked fine, however, on a couple of systems a strange error was encountered after the migration. The LPAR was booted into AIX 6.1 and everything came up fine.

(with the –O flag for a device reset) to clone rootvg to an alternate disk
which is then replicated to DR. These methods may work but are cumbersome to
