Trying to upgrade to CPS18; psi_iir.xml seems to be wrong
Version: Windchill 12.0
Use Case: The CPS18 staging dir does not contain an iinnnnnnn file in any of the instreg directories
Description:
I am still having trouble (you will see a recent question with a similar name).
The psi_iir.xml file under ~/.ptc/windchill/psi_iir_index.xml contains:
<Instance location="/opt/ptc/Windchill_12/PSI" id="ii nnn
with an old id corresponding to an iinnn directory under my CPS11 staging directory.
The new (CPS18) staging dir does not contain an iinnnnnnn file in any of the instreg directories:
CPS18/windchill_12.0.2.18_service_pack/Disk1/InstallerData/instreg
Am I supposed to create the new iinnn directory in the CPS18 staging directory manually? The PSI installer does not create it.
Maybe I should move the iinnn file from the old CPS11 staging directory to the new staging directory? That seems incorrect.
I have read many articles and help pages; what doco addresses this issue?
