Re: Do you freeze your PTFs when preparing to migrate?

I never thought of that. Then it's a good idea.Thanks for sharing.

Until the end of March can you please defer all PTF’s and cumes

I normally check for HIPER and other PTFs every Friday. It seems
strange to me to have a freeze period for the next 7 weeks. If it
was me, I'd want to make sure I had the latest fixes.

Two questions:
1.  Is there an IBM recommended practice on this?
2.  What strategy are you using?

   I have heard of employing that strategy, as a means to help identify
what is the origin for any changes in operation\performance; the hdw vs
the sfw.

   Holding the software in stasis over a period preceding the hardware
change can give better assurance that changes [for better or for worse]
were due to the change in hardware.  IIRC, that particular transition
comes with a required re-translation, so that hardware change is an
implicit software change, at least for the applications.?
