Migration to AIX PCM combined with OS update using Alternate Disk Copy

On most AIX systems the SP or TL level is updated at regular intervals. It makes sense to perform the migration from SDDPCM to AIX PCM together with such an update. This saves time and some reboots, which otherwise have to be done because of the multipathing migration. The migration from SDDPCM to AIX-PCM, as part of an OS update, using the Alternate Disk Copy method, is shown in more detail here:
