What to do w/ ODM and PP when I upgrade AIX?

I have several IBM AIX servers that I'd like to upgrade.  Below are some pertinent information:

Hardware Platform:  IBM Power 5 (P5-590)

Current OS:  AIX 5.3 TL8 SP3

New OS:  AIX 6.1 TL6 SP1

ODM:  5.3.0.1

PowerPath:  5.1.0.0

SYMCLI:  6.5.3.0

What should I plan for during this OS upgrade, and in what sequence?  The PP documentation for 5.3 indicates that in a AIX upgrade, I will need to uninstall PP first, upgrade AIX, then reinstall PP.  But this information is not in the PP documentation for 5.1.  Also, there is no information regarding the ODM in the event of an AIX upgrade.

Thanks in advance!
