Why are my source types missing after upgrading to Splunk Enterprise 7.2?

Upgraded search head to 7.2, and whenever I search for logs, the majority of source types appear to be missing from the list of available source types.

If I do a search for a particular source, and add "| fields host source sourcetype", the source type is not returned.

If I do a metadata search, or a search from my cluster master for the data, the source types are returned fine. This seems to be a problem only with my upgraded search head.

Upon reviewing configs, there were stanzas in ..etc/search/local/props.conf and ..etc/system/local/props.conf like this:

[host::t]
FIELDALIAS-t
sourcedFromas_sourcetype = sourcedFrom AS sourcetype sourcedfrom AS sourcetype

[host::pcf]
FIELDALIAS-pcfStacktraceasStackTrace = Stacktrace AS StackTrace
FIELDALIAS-pcf
sourcedFromassourcetype = sourcedFrom AS sourcetype sourcedfrom AS sourcetype

[host::*]
FIELDALIAS-allhostsourcedFromas_sourcetype = sourcedFrom AS sourcetype sourcedfrom AS sourcetype

Field aliasing has been changed in 7.2 and these entries broke sourcetypes on the production search head. Once they were removed, and the search head was restarted, the problem was fixed.

Was there anything in the documentation about this change? It kind of seems like a big one, and I don't see anything in upgrade notes or anything in the release notes, and it's kind of biting me right now.

I am pushing internally to have something added to the documentation about this, as I believe you are correct and currently there is nothing that denotes this change.

Hello,

I know this question has been a while but what exactly is wrong with those FIELDALIAS entries? We seem to have encountered the same error upgrading from 7.1.4 to 7.3.2.
