Upgrading Nokia UTRAN RU30 VS (Vendor Specific) and VNLM (Vendor Neutral Loadmap) Tech Pack.
Issues were found during RU10 VNLM upgrade to RU30 VNLM (with combination of RU20 VS upgrade to RU30 VS). Because there was no RU20 VNLM hence the merging of RU20 VS with RU10 VNLM was throwing some errors in vmm-server.log file.
Below is an illustration of the upgrade path.
The upgrade path above is INVALID. Different versions of VS and VNLM Tech Pack should not be merged in the first place. We should only install matching versions of VS and VNLM Tech Pack.
This has already been highlighted in the TNPMW Techpack Installation Guide. See the snippet below:
Never attempt to merge different version of VS and VNLM Tech Packs.
