Mentioned in SAL (#wikimedia-operations) [2016-11-14T13:39:01Z] <marostegui> Stopping replication in db2066 for maintenance - T150518

I have started to transfer dewiki to dbstore2001 from db2066

The transfer finished for both, dewiki and wikidatawiki.
I am now importing dewiki's tablespace.

dewiki tablespace got imported.
Now the import is happening on wikidatawiki

The import went fine and dbstore2001's s5 instance is catching up. I will start the compression and then the import to dbstore2002.

S5 caught up and was compressed.
I have started the transfer to dbstore2002 now.

dbstore2002 got all the tables imported from dewiki and wikidatawiki and it is now catching up with the master.
