Our setup has one location with a pair of multi-masters (call it "location
A") and another location with a pair of consumers (call it "location B".
I'd like to "switch directions" between the locations so the servers in
"location B" will be multi-masters between themselves and the servers in
location "A" will be "downgraded" to simple consumers.
As far as I understand the documentation, this might be possible by adding
the "missing replication agreements (i.e. tell the "location B" servers to
become multi-masters and tell the current multi-masters in "location A" to
also accept updates from "location B").
Effectively, this should convert the current two-way multi-master cluster in
"location A" into a four-way multi-master cluster across "location A"
"location B". Once this is done I expect that I can "downgrade" the
"location A" servers to simple consumers by removing the current replication
agreement they have (or even replace them with a new installation altogether
if that's not possible).
Am I correct or is it more complicated than that?
