Yuval,
I just uploaded a fresh tarball to file-storage, with the scripts we used when we migrated Openacs.org from 3.x to 4.5. (I should have done this a long time ago, I know, but better late than never ...)
https://openacs.org/storage/download/bboard-migr.tar.gz?version_id=98970
This may be of interest to you if you haven't already done most of the moving ...
There is no script for migrating tickets though.
The contents of the README:TXT in the tarball is also available here:
https://openacs.org/plan/walkthru/
(the people behind these scrips are, _I think_, someone from Museatech, Jeff Davis, Tilmann Singer, Dave Bauer and myself - the blame is well spread 😊)
Good luck with the migration!
