IBM AIX upgrade OS from 5.1 to 5.3

I am an Oracle DBA that does some admin maintenance on our UNIX and Linux systems.
Recently I have been tasked to Upgrade our AIX servers from 5100-08 to 5300-05.
I need to come up with a timeline and what resources will be needed by COB.

Servers:
P630's & P615
Storage: IBM FastT600

Anyone have an educated guess on how long this will take?
Any chance to get some step-by-step guide for doing this?
Any special recommendations?
Best practices?
safety tips?

Thanks in advance.

Hi rksfannin,

That's a relatively small upgrade that can be performed quickly, probably less than an hour per system.

Insert the CD into the Server and use 'smit' to start the upgrade. Depending on the products that you have installed this might be so easy as to not require any more intervention on your part.

Good Luck,
Kent

Uhh-huhh - make mksysb backup of system, then backup of every volume group, and backup of every database software using raw slices.

Hi gheist,

I don't recall any issues when upgrading to 5.3. (Of course my memory may be failing me......)

Yes. The system has to be booted (several times as I recall) but that's typical.

Does anyone know where to find an IBM guide for this upgrade? Not that I do not trust the replies, I would just prefer some something from IBM. I have been looking ,but the IBM site is dificult to navigate through.
