This should be no problem at all - you just shut down the slave,
upgrade it, and replication should pick up again when you
restart. Then you can upgrade the master. This is the same as it was
with 3.x to 4.x.

Generally, you want your slaves to be the same version as the master,
but if that's not possible (as in when you upgrade), then the slaves
must be higher version than the master.
