the original poster didn't say whether the services were from ports
and/or base

if from ports only then your suggestion (3c) could perhaps lead to
problems (that is upgrading base and not upgrading ports, or am i wrong
here ?)

FYI, from experience i know that e.g. the config-file of dovecot changed
(different syntax), so you can't just switch from 4.x to 6.x and keep
all your config-files from the old setup for software from the ports

in that case you need to first get a working setup for your services for
6.x before switching completely, but other than that the original plan
sounds good
