I’m quite happy go with a SWAT deployment and I agree that it’s probably a
lot safer.
My only concern with that is that between the 2 tasks it would be 5/6
patches in the SWAT window.
It would also be my first mediawiki core + extensions SWAT so are the
patches safe to +2 during / just before SWAT or Should I get that done
before?
Thanks,
Samuel

with being deployed as close together as possible to avoid
inconsistently translated namespaces.
Would as mentioned SWAT be better for all 5 patches or should we let what
can ride with the train and deploy the one config patch shortly after and
run for both wikis in that window? or could we ask the train runners to do
that?
What you're describing sounds like it would be a good candidate for SWAT
deployment. My reasoning is that (1) it is atypical to run maintenance
scripts as part of the train and (2) there are no guarantees that a
train won't rollback.
That is, backporting to a version that is stable ensures that we don't
end up having rolled forward to all wikis, run the maintenance script,
and then having to rollback due to an unrelated problem. Additionally,
the log triage that follows a train window may mean that we can't
guarantee a timely deploy of the configuration change following train.
To me, this feels safer/faster/easier as a SWAT deployment; even though
this might make for a particularly long SWAT window.
Thanks!
