Hi,
We've upgraded SP2010 to SP2013 (not the 1st time). Previously we had Vizit solution deployed but we've removed it before upgrading.
For some reason, Health analyzer finds Missing Feature that does not exist in mentioned DBs (2 of them).
With Vizit support we've run query on content DB and no ID could be found. So, how come Health Analyzer still finds it? Mentioned ID below is known Vizit feature ID.
[MissingFeature] Database [WSS_Content_80] has reference(s) to a missing feature: Id = [ec662500-768e-4603-9963-d38f185ded4a]. The feature with Id ec662500-768e-4603-9963-d38f185ded4a is referenced in the database [WSS_Content_80], but is not installed on the current farm. The missing feature may cause upgrade to fail. Please install any solution which contains the feature and restart upgrade if necessary.
Things I've already done:
1) Cleared Farm cache
2) Restarted all servers, including SQL
3) Rerun Health Analyzer a million times
4) Run query on SQL: SELECT * FROM WSS_Content_80.dbo.Features WHERE FeatureId = 'ec662500-768e-4603-9963-d38f185ded4a'
