These are the minimums but higher service packs are recommended.

Notes:

1. AIX 6 is highly recommended as the default install to ensure simple updates (you will then avoid the upgrade to 6.1, as AIX 5.3 is eventually phased out).
2. - means this combination is not supported.
3. * means no service pack needed ... but I always recommend adding the first service pack (as soon as it is available) to avoid early problems that are already fixed.
4. AIX 5.2 TL10 SP8 is supported via AIX7, POWER7 and Versioned WPARs.
5. Other AIX releases and Technology Levels are not supported.
