I already upgraded many customer environments from IBM Sametime 8.5.2 to 8.5.2 IFR1 without any hitches but this time I tried it on our own internal production environment and failed miserably.
Don’t ask me why but the upgrade of the SSC failed and my system was left in an “unstable state”
Definition of unstable = I can’t install the upgrade, SSC is not working, I can’t reinstall 8.5.2
Fortunately I found a Technote which rescued me out of this unstable state and helped me to go one step forward
Upgrading Sametime System Console to 8.5.2 IFR 1 fails during installation
But still the upgrade failed and by searching for errors inside the logs (yes, there are many, many logs and it will take a while to find useful infos) I found a possible credential problem. I remembered an upgrade preparation step
Updating Installation Manager if the administrator name or password has changed
which I ignored because I never changed the admin account or password.
I checked the encoded wasadmin password in the installregistry.xml file and surprise, surprise, it was not the current admin password.
After changing the password the upgrade worked as expected.
Always check the wasadmin password, even when you didn’t change anything
Download the iscmod_uninstall.py from the technote, it will be a good friend if anything goes wrong
