      Description

      I have a .xar backup package of my whole wiki, created by xwiki 3.0 instance. After unsuccessfull upgrade (see XWIKI-7388) I decided to start with a fresh new database. I've created an empty database, launched a 3.3 xwiki instance pointing to it, imported my .xar to the wiki (filesystem based attachment store set in xwiki.cfg) - without problems.

      Now, when I try to display content of the uploaded package - I have an error (logs at the bottom). When i unzip the .xar file, remove from it documents with attachments (stored in documents) and create and upload .xar file again - I can display its contents without problems.

      My source xwiki installation was upgraded many times (it is a few years old), mostly without problems, attachments are working ok, but my source db schema differs from the schema created by 3.3 version. The column xwa_content of xwikiattachment_content table and xwa_archive of the xwikiattachment_archive tables are (in the source db) of type bytea; 3.3 version created them with type oid.

      How can I deal with this problem? Try to find a solution for manual DB migration?

      This is the exception i get in catalina.out:
