Upgrade procedure for 9.0 with HS/SR ... ?

What is the recommended procedure for this?

For instance, normally I would do a dump, upgrade, reload, when dealing 
with a single server, just to make sure all my system tables and such are 
clean ... but, if I have HS/SR setup to a slave, what is the recommended 
method of doing an upgrade?

This will be of more concern later, I imagine, when we're dealing with a 
9.0 -> 9.1 upgrade ...
