AIX Migration from 5.3 to 6.1 using NIM

Prechecks before the upgradation.

1)      Please check if the hardware supports the 6.1. It should be minimum a Power4 processor machine.

2)      Check for the microcode level of the machine. It should be the latest.

3)      Collect the system information.

4)      Ensure the filesets are in consistent level.

instfix –i | grep –i ML & instfix –i | grep –i sp

5)      Check for the broken filesets, lppchk –vm3

6)      Check for the Emergency fixes, emgr –P, if any remove it with emgr –rL <Label Name>

7)      Take the latest mksysb backup and sftp it to the nim server – rsmnim03 in the location “/migration-mksysb”

8)      Ensure there is a minimum of 1GB of free space on rootvg. Also /usr and /tmp should have sufficient free space.

9)      Ensure the console is working.

10) Perform the alt disk clone of the current status to the other free disk, ‘smitty alt_disk_install’, such that in case of migration failure, we just have to reboot from the clone disk to revert to the previous working state. Let this clone remain for 2 days after migration for safer side.

11) Check with the application team, if the currently running applications would work fine with the 6.1 after the migration is over.

12) Change the bootlist information.                                                   Syntax,                                                                               bootlist -m normal ent0 gateway=0.0.0.0 bserver=10.1.12.1 client=<Client-ip> hdisk0 hdisk1                                                              Example,                                                                                                     bootlist -m normal ent0 gateway=0.0.0.0 bserver=10.1.12.1 client=10.1.7.107  hdisk0 hdisk1
