We are doing a re-arch of how wikireplicas work, in that process we are deprecating multi-source for many well known reasons.
labsdb1009-labsdb1011 will be replaced by clouddb hosts: T267090
labsdb1012 needs to be converted from multi-source to multi-instance.
@Bstorm has worked a lot to create some puppet roles for these new hosts, so I guess labsdb1012 will need to get one of them: https://gerrit.wikimedia.org/r/c/operations/puppet/+/639815
@elukey we are still far from having to tackle this (we are aiming for the end of March to have everything ready), but can you take a look from your side to see if there would be something else needed puppet-wise or it would be enough with what Brooke has already developed.
Note: labsdb1012 cannot be taken down during the first week of the month.
