We can edit summaries and comments, presumably by API calls as well as by
the web UI. So how about this:
Step 1: Preallocate sufficient github issue numbers. Make a bot account and
with it file empty placeholder issues until we have N issues total, where N
is the number of bugzilla bugs.
Step 2: Shut down the ability to file new bugzilla bugs, double-check we
have enough placeholder bugs, then open up github for new issue
submissions. Change llvm.org/PRxxxxx to redirect to github for xxxxx's
higher than the transition point.
Step 3a: For each issue filed by the bot account, sync that bug's contents
to the bugzilla entry: copy across the subject, all the comments, tags, and
Step 3b: For each issue not filed by the bot account whose number is that
of a bugzilla entry, file a new github bug and sync it with the bugzilla
bug then add a tracking comment to the github bug saying what the new
All we would need to do before we switch systems is steps 1 and 2. The data
import can be done incrementally with no time constraints. Once transition
is complete, we can change llvm.org/PRxxxxx (and existing bugzilla links,
since I'm sure they exist in the wild too) to redirect to github, and shut
down our bugzilla instance.
If new PRs are filed during step 1, we get new "problem" issue numbers,
which we deal with in the same way as the 210 existing github issue numbers.
