Paul,
The link_bibs_to_authorities.pl script is hardcoded to ALWAYS erase manual links. I'm not sure what the reasoning is behind that. But, every time you run it, any link you've done manually that the script can't automatically figure out will be removed. Nature of the beast (for now, at least).

Im assuming you did this on your testing/staging server right?
Id restore that from backup, then try applying the patch and see if you get better behaviour.If so, then do it on your production machine.

Following difficulties we have had migrating 3.2 to 3.6.1, someone on the users mailing list suggested we should run link_bibs_to_authorities.pl -- (db has ~10k authorities and ~15k biblios) -- so I did just that, and have APPARENTLY DEMOLISHED *EVERY* LINK IN THE DB. From my notes:
paul@nelson:/usr/share/koha$ ./bin/link_bibs_to_authorities.pl
Bib authority heading linking report
------------------------------------
Number of bibs checked: 14911
Number of bibs modified: 14886
Number of bibs with errors: 0
but - the staff interface no longer correctly finds authorities !!!
[1] Manually link (staff client) auth "Lubbock" to bib "Arctic Whalers" -- now linked, 35 other Lubbock bibs not linked. Is this a question of zebra re-indexing?
So: KOHA_CONF=/etc/koha/koha-conf.xml PERL5LIB=/usr/share/koha/lib ./bin/migration_tools/rebuild_zebra.pl -a -r -v
and KOHA_CONF=/etc/koha/koha-conf.xml PERL5LIB=/usr/share/koha/lib ./bin/migration_tools/rebuild_zebra.pl -b -r -v -x
koha@nelson:/usr/share/koha$ ./bin/link_bibs_to_authorities.pl
... processed 100 records
/ ... /
... processed 14900 records
Bib authority heading linking report
------------------------------------
Number of bibs checked: 14911
Number of bibs modified: 1
Number of bibs with errors: 0
koha@nelson:/usr/share/koha$
All this did was to *un-link" the bib/auth link that I had manually entered at [1] above. Could someone involved with signing off bug 5683 please explain why link==unlink?
Help - please.
Paul
