Migrating MediaWiki Sites over to Windows Sharepoint Services Wiki

For Bugzilla, Trac has a script bugzilla2trac.py that will automate the process of importing Bugzilla bugs to Trac tickets for you. Of course, Trac doesn't have support for blocking/blockedby tickets out of the box, so if you want to import this data too, you'll have to use the MasterTicketsPlugin and then modify the script yourself (which is what we did when we migrated).

In the interest of helping other people with this question, here's the answer:

"I modified the WSS registry area instead, and it worked. "

In other words, you have to tweak the registry bits allocated to the WSS version rather than the MOSS version.
