IBM Power Systems to AIX version maps

Do you need to check whether the version of AIX installed in your environment is supported on new Power server?

I've migrated LPAR with AIX 5.3 TL12 SP4 from Power 570 running on Power 6 CPU to Power 710 server and AIX have not known PCIe ethernet adapter.

So I have had to upgrade AIX to version 6.1 in order to have this device supported.

Let's check AIX to Power system dependency on IBM Website "System to AIX maps".

Compatibility can be also checked on "Fix Level Recommendation Tool" website:
