Versioninfo.xml missing

OK,

I migrated an EV11.0.x to 12.0

So far so good, DB were upgraded without any problem.

Services started normally but, at one, the indexing stopped.

Looking further in the event viewer I saw this

An unexpected error has occurred.

Error Summary: Indexing Service start up error
Error Details: Could not find file 'C:\Program Files (x86)\Enterprise Vault\EVIndexing\data\InitialConfigurationData\indexmetadata\VersionInfo.xml'.

I di try to copy the versioninfo.xml from the old to the new server. No can do. the file is deleted when the indexing service start.

Idea how to resolve this?

Cheers,
