Hi ,
I made it befre, Below are the stepsof what i did:
backup the AIX v5.3 on the 570 server (mksysb) and create the new partiton on the 750 machine and restore from the mksysb image,
and put AX v7.1 media (DVD) (or any way of migration NIM fo example) and choose migration as the installation method ,
But the very importanat thing is to check your application compatability i it runs on AIX v7.1 ,

This is what i made and it works ,
But i think this is not the best scenario ,but it works

Thanks Ahmed.
That's means AIX 5.3 is supported in p770, right?.
If I have oracle binaries & data on SAN, say inside dbvg, could I just do savevg dbvg, then restorevg dbvg on restored mksysb aix5.3 at p770. Then from this point only I start upgrading the OS to AIX7.1. Will it work this way??

For your requirement

Option : 1

Get an alternate disk to the server which you want to migrate.
Configure this server as NIM client on the NIM server.
From the NIM server -

smit nim
-> Perform NIM Software Installation and Maintenance Tasks
-> Alternate Disk Installation
-> NIM Alternate Disk Migration
-> Perform NIM Alternate Disk Migration

• Target NIM Client [] +
• NIM LPP_SOURCE resource [] +
• NIM SPOT resource [] +
• Target Disk(s) to install []

Requirements -

AIX 7.1 LPP source
AIX 7.1 SPOT
Alternate disk on the client (mentioned above)
Take a latest mksysb backup and TSM backup.

This can be performed online, once this process completes, you verify this smit output and check the bootlist and reboot the server after your applications are down. It may take 15-20 minutes downtime approximately.
Option :2

Get an alternate disk to the server which you want to migrate.
Configure this server as NIM client on the NIM server.
From the NIM server -

Take the mksysb backup from the server.
Convert the mksysb image to AIX 7.1 from AIX 5.3

nimadm -T mksysb_<server>_53 -O /location/mksysb_<server>_71 -s spot_aix71 -l lpp_source_aix71 -j vgname -Y -N mksysb_<server>_71

By this method you can convert the image to AIX 7.1 offline and you need to perform the normal mksysb restoration to the LPAR with AIX 7.1 image on new requested disk.

Network traffic will not happen on your production server since the conversation process is performed on the NIM server using Disk Caching.

Before performing any of this options, you need to check with your application team to ensure that their application will support AIX 7.1 or not.

Incase of backput boot the server with the alternate disk from SMS.
