I only bother with that prior to an upgrade. PTFs that are superseded by PTFs in the later Cume or Group will automatically be permanently apply during the load. I want to keep PTFs as temporarily applied for as long as possible--gives me more flexibility in managing them even though I can recall the last time I needed to remove an IBM PTFs for being defective.

We do PTF
maintenance for almost all of our customers on a quarterly basis.
Therefore, I know that they have been running on the "B" side fine for the
past 3 or 4 months. I want to insure if we are to have a problem with the
installation of this new set of PTFs, I could reboot from the A side. So,
by coping the B side to the A side (which is what you are in essence doing
when your permanently apply your PTFs), I know that I can reboot the machine
and be running the same version of microcode that I was running before the
PTF installation.

Note that A-side and B-side are relevant only for micro-code PTFs. They have no bearing on OS or LPP PTFs.
