    Description

      Steps to reproduce:

      • Setup a 4.5.4 XEM (with DW instalation) and install the Workspace Template + 3 subwikis
      • Migrate the wiki instance to 5.3
      • You will see stacktraces before the 5.3 DW kicks in
      • having only the main wiki does not reproduce the issue
      • I only reproduce this on Oracle using a slow machine, but I'm almost sure this is not an Oracle issue, but more a slowness of the machine issue. The other machines I tested on were much faster.

      It seems that db's migration is not finished before SOLR Indexer wants to start indexing, thus triggering db migrations in parallel.

      Here is a stacktrace
