      Description

      I am upgrading an XWiki instance to 11.10.5.

      Just after having installed the new XWiki package with debian, I restart Tomcat, so during R1100000XWIKI15620DataMigration is processing.

      Then, when I try to reach the wiki, I get an error saying R1100000XWIKI15620DataMigration has failed.

      Root cause:

      org.apache.commons.io.FileExistsException: Destination '/var/lib/xwiki/data/store/file/xwiki' already exists

      My theory is that the directory /var/lib/xwiki/data/store/file/xwiki is created at the beginning of the migration, and when the migration is re-applied, it failed because it sees that /var/lib/xwiki/data/store/file/xwiki exists.
      In other words: the migration seems to not be able to resume when stopped in the middle.

      At this point it is only a theory, I would like Thomas Mortagne to confirm when he can.
