That's an exercise left to the reader :)
Honestly, I don't think you need to. Why would you? The handler does not do
anything if never called.

One Solr server does not know about the other, so you do not need to "switch"
anything
on the Solr side. You simply need to design your client in such a way that it
handles
the operations in correct order and timing, i.e. that it pauses all feeding
until replication
is done, then feeds to the new master instead of the old.
