As Daniel alluded to, the only issue I really have is moving _all_ the
kernel repos at once. At the end of the year we'll have easy automatic
scaling thanks to the independent services being separated. As it is,
all the GitLab services (apart from CI runners) run on a single
machine, so we have limited options if it becomes overwhelmed with
load.

Do you have a particular concern about the repos? e.g. what would you
check for to make sure things are 'there and working'?

When bugs are migrated from Bugzilla to GitLab, only open bugs are
migrated. Closed ones are left in place, as is; open ones have a
comment at the end saying that the bug has moved to GitLab, a URL
linking to the new GitLab issue, and telling them to please chase it
up there.

Even when we move everyone completely off Bugzilla, we will keep it as
a read-only mirror forever. Even with Phabricator, which very few
people ever used, has had all its bugs and code review captured and
archived, so we can continue to preserve all the old content and
links, without having to run the actual service.

Cheers,
Daniel
