Note: Please go through the AIX 6.1 release notes before start the migration.
Pre-migration:
Pre-migration script will come along with the AIX 6.1 DVD1. We should run this script to check the server feasibility before start the migration. There is no downtime involved to run this script. We have to copy this script to the /tmp directory from the AIX installation media and should run from /tmp. The output of this script will save under /home/pre_migration. It is must to read all the files and do the necessary actions before start the actual migration.
Sample execution of pre_migration script:
Insert the AIX 6.1 TL07 installation media to the drive.
# cp /mnt/usr/lpp/bos/pre_migration /tmp
# cd /tmp
# ./pre_migration
All saved information can be found in: /home/pre_migration.090903105452
Checking size of boot logical volume (hd5).
Your rootvg has mirrored logical volumes (copies greater than 1)
Recommendation: Break existing mirrors before migrating.
Listing software that will be removed from the system.
Listing configuration files that will not be merged.

Saving configuration files that will be merged.
Running lppchk commands. This may take awhile.

It is recommended that you create a bootable system backup of your system
before migrating.
Sample files:
configuration_files_being_merged
configuration_files_missing_from_system

other_software_being_removed

Note: I have done this migration by using alt_disk_copy method since we don’t have a NIM setup in the environment.
Procedure:
# bosboot -a
# unmirrorvg rootvg hdisk1
# reducevg rootvg hdisk1
# alt_disk_copy -d hdisk1

Bootlist is set to the boot disk: hdisk1
# shutdown -Fr
Note: I have rebooted the server with hdisk1 as a bootdisk to check the status and I have done this migration on the hdisk1 so that we can have the undisturbed hdisk0 for the backout.
After the server come up with hdisk1 for the first time please check the general configurations. If everything fine then again reboot the server (Make sure the AIX 6.1 Installation DVD is inserted already) and start the AIX migration on hdisk1.
# shutdown -Fr
Steps:
1. Choose the SMS mode
2. Choose the boot device as cd0
3. Select current console as the system console when prompted.
4. Select English language when prompted.
5. Type 2 to select Change/Show Installation Settings and Install to make sure the installation type is Migration and verify the selected disks to install. Press Enter to confirm and begin the migration installation. After the BOS installation is complete, the system automatically reboots.
Note: Please consider the output of “lsdev -Cc disk” since here the hdisk number might be different than the actual configuration so it is always good to choose the right disks by comparing the “lsdev -Cc disk” command output.
Eg:
hdisk0 Available 04-08-00-5,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 04-08-00-8,0 16 Bit LVD SCSI Disk Drive
