s5 (dewiki) is the next cluster for re-setup. I already got a fresh dump from
the WMF and imported it too on a server. The next step is to move the user-
databases over. For this I have to switch s5 into read-only. The read-only-
phase will start at
Tomorrow, Thursday after 13:00 UTC.
s5 carries a few very big user-databases, so I think the movement will take
more an 1 day. Below is a list of the biggest user-databases, maybe their
owners can take a look if some clean-up is possible?
Unfortunately s5 can not stay at the new place because the server belongs to
OSM. So a second read-only-phase will happen in near future (that one should
be a bit faster because I will just rsync files around instead of importing).
u_lvova_golem_XXX databases are safe to skip during the move. Golem will re-create those bases on the new host. Size of those bases depends on actual connectivity situation and after re-creation the size will be similar to what it is now.
By the way, I've found s2 to be much slower after re-setup than the server, which handled both previously, s2 and s5.

I just found (ok, Nosy pointed me) an eMail by Asher telling me that in
addition to the movement of wikidata from s2 to s5 (see my other mail) the WMF
also made some shema-changes on s5 (I guess only on wikidata, but not sure)
which are not in the binlogs and therefor we have to re-import s5 to make sure
we have all data.
For this reason there will be no movement of the user-databases today (I will
switch s5 back to read/write in a moment). I will message you again when we
are ready but it will take at least 2 days.
Most certainly we will also have no up2date wikidata-data for the same
