I do that all the time.

No, but as long as you don't use the other one's extra binaries it
doesn't matter.

v2.0 can read most v1.x config files, but it'll give a lot of warnings
about it. Their default configs are anyway in different locations. I
just keep them both:

v1.x: /usr/local/etc/dovecot.conf
v2.x: /usr/local/etc/dovecot/dovecot.conf

./configure --prefix=/usr/local/dovecot-2.0
