I think so.  Generally, during an upgrade:

 - daemons are stopped in prerm before the package is removed.
 - the packge to upgrade is removed.
 - `update-rc.d DAEMON remove` is done in postrm.
 - the new package is installed.
 - `update-rc.d DAEMON defaults; /etc/init.d/DAEMON start; is
    done in the postinst of the new replacement package.

AFAIK, there is currently no way of `registering' update-rc.d
commands such that they are repested after an upgrade.
