Does anyone know how to overcome the problem below?
We are upgrading uCMDB 8.07 to 9.05 The upgrade process fails in the 'Validate and upgrade the class model' step. Already tried to rerun several times the tool without success.
The error.log reports: ERROR - upgrade error for [validateClassModelAndUpgrade] java.lang.IllegalArgumentException: User class model is not valid for upgrade. Please see details in logs. These problems must be fixed before continuation of upgrade process.
The error realted to the class model different from what 9.05 expected to see in your 8.07 system.
The deployment guide for UCMDB 9.05 has Prereuisitesfor upgrade section on p.62.
If you have Discovery and Integration Content Pack 7.00 or earlier, you must install Content Pack 8.00. This step must be performed after upgrading to version 8.04 or later.
Please pay attention to following:
Note: When upgrading from UCMDB 8.0x to 9.05, the highest Content Pack version you can run is version 8.00. You cannot install Content Pack 10.00 with the upgrade. However, after upgrading UCMDB, you can upgrade the Content Pack version separately.
In addition, I'd suggest installation latest CUP on top of 9.05 codebase prior to starting of Upgrade. Several upgrade related bug were fixed in CUPs.
