Matyi,

I am redirecting your email to the Debian cyrus package maintenance
mailinglist, as the other co-maintainers are more versed on this upgrade
procedure than I am.

You need the db_upgrade utility for the *target* libdb version, i.e. you
need the one from Berkeley DB 4.2.  It is in the package db4.2-util and it
is called db4.2_upgrade.

I will leave your other questions and suggestions on improvement for the
other co-maintainers to address.
