what level of AIX 5.2 w/ Cloverleaf 5.2

We are wanting to upgrade our OS unde our current Cloverleaf version of 5.2  .  We are at AIX 5.1 but wish to upgrade to 5.2  .  Once the upgrade is complete, we want to be able to jump to Cloverleaf 5.4  .  What is the greatest level that Cloverleaf 5.2 can accept.

Thanks.
