Hey Tim, I recently went through a similar upgrade. We are connected to Seimens Invision and I ended up establishing my new box as a seperate PU with a whole new set of LUs. I had a similar error that you saw in your error log that was resolved once Seimens rebuilt or enabled something on the CICS side. Are you connecting the new box to the old LUs or are these new LUs? Took me awhile to convince seimens to even look at thier side as they kept assuring me everything was setup right.
Mike
‘Morning, all,
We’re in the process of moving/upgrading one of our engines from 3.8.1P on AIX 5.1 to another box on 5.3 and AIX 5.2.
