Hi Tom.

I haven't read all the replies before mine. Sorry if my idea overlaps with
someone else's.

I have a proposal for the issue migration from bugzilla to github. You
mentioned in the ML thread that proposal 1 and 2 were favored because they
can be done sooner than proposal 3.

In order to begin with proposal 1 and 2, what if you created dummy issues
in github for the number of bug-ranges 1-XXXXX, where XXXXX is the highest
number in bugzilla? When this is done by a script you could add a special
label to those issues that mark them as bugs that are still managed by
bugzilla. For the description you could put the link to the bugzilla
instance and a text that "this bug is still managed by bugzilla".

If you immediately close those bugs, then they don't show up. BUUUUUT IIRC
github has this odd way of numbering bugs and issues. Issues and Pull
Requests share the same pool of numbers. I'm sure you know that. But as
long as you disallow creation of NEW bugs in bugzilla, have created the
dummy issues in github, and don't open any PR in github this should be good.

Then at some point you can move over all the bugs in bugzilla to their
dummy issues in github. The latter just serve as placeholders until then.

I hope this makes sense.

Regards
Konrad
