Full Discussion: Upgrading AIX Unix
Operating Systems AIX Upgrading AIX Unix Post 42705 by tommy on Monday 3rd of November 2003 05:08:53 AM
Old 11-03-2003
As Optimus_P already said upgrading AIX is always done following way:

1. Make system backup (smitty mksysb)

2. Make optional backup of other volume groups (smitty savevg)

3. Read carefully through AIX Release notes to determinate right upgrade path. (e.g. from AIX4.3.3 to AIX5.1 you have to use migration upgrade, from AIX4.3.2 to AIX4.3.3 smitty update_all was enough).

4. Add "latest" fixes to system (when this was written they could be found from: IBM eServer pSeries support site)

5. After upgrade check what non-os-related bffs (e.g. HACMP, TSM Client, ..) need to upgrade with command "lppchk -v -m3" and upgrade them.

6. Upgrade all other software that might need upgrading.

For more information about AIX upgrade please refer to AIX Version 4.3 to 5L Migration Guide.

And yes, IBM is dropping support for AIX4.3.3 end of 2003 so you should upgrade your AIX boxes directly to AIX5L.
