In case you're using version HACMP 5.4.0, then you would have to first upgrade to HA 5.4.1 with some Service Packs. Follow it up with AIX upgrade or migration , depending on the current AIX level. You would need to be at AIX 6.1 TL6 or AIX 7.1 in case you want to go to PowerHA 7.1.0. If the target PowerHA version is 7.1.1 then you would need AIX 6.1 TL7 or AIX 7.1 TL1 and for PowerHA 7.1.2 the required levels are AIX 6.1 TL8 or AIX 7.1 TL2. Post AIX upgrade you can either choose rolling or snapshot or offline migration paths depending on the maintenance window you have. You can refer PowerHA 7.1 redbook for the steps
