Thanks for your procedure tips, that's pretty much the same procedure I use 
except that I didn't even demote the "a" machine before upgrading it. Now I 
guess demoting the machine in question before upgrading it is the best practice 
and so I checked the OpenBSD FAQ about CARP and see different methods. The 
"carpdemote" way seems the cleanest way so as I have 8 carp interfaces all in 
the default carp group, should I simply run the following command:

$ ifconfig -g carp carpdemote 50

or what is your way of demoting the server before upgading it?
