Here’s what happened:
1. Our central repository with the full complement of largefiles went
down
2. I published my personal copy as a new central repository
3. People pushed to it and now it’s ahead of the old repository,
including new largefiles
4. I’ve regained access to the old repository
Question: How do I transfer largefiles from the old central repository
to the new central repository so it has a full complement? I must do so
while preserving any new largefiles that have since been pushed to the
new repository.
The blobs are stored in ".hg/largefiles". So as long as you don't delete
anything from there on the server, you should be able to add the missing
ones from your local repo.
Alternately if you want, you can `hg serve` your full repo, and then
update to each rev in the repo on the server. (You will need to
explicitly set paths.default to your full repo). This will fetch the
missing files, and cache them in the global store as well as the repo
itself.
Alternatively: what is the right thing to do in this situation such that
I end up with a fully complete central repository with all new and old
largefiles?
The problem with the new central repository is that cloning to a machine
that has an empty local largefile cache crashes server side (and hangs
client side at “getting changed largefiles”) with:

Server side mercurial version is 4.0 (from Debian 9’s default repo).
You might want to upgrade the server version, even if you have to build
from source. I can't say that a lot has changed in largefiles in the last
2.5+ years, but I'm sure there have been some fixes and changes.
Thank you for your time,
Ansis.
