Information in this document applies to any platform.
We upgraded OBIEE 220.127.116.11.9 to OBIEE 18.104.22.168 and then rolled back the change by restoring file system backup of OBIEE and restored the schemas of MDS and BIPLATFORM.
After restart of OBI, it was all fine with OBIEE 22.214.171.124.9 as expected.
But when we tried to perform the upgrade to OBIEE 126.96.36.199 again, the schema upgrade step failed stating the components are already upgraded. When we looked into SCHEMA_VERSION_REGISTRY, it shows version as 188.8.131.52 and that seems to be the reason Patch Set Assistant (psa) utility thinks it is already upgraded while it is not.
