For each of lucid → precise, precise → trusty, and trusty → utopic, I tested as follows:
1) Set man-db/auto-update to false and install man-db from -proposed. Check that /var/cache/man/index.db is not created. Install vim and check that it is still not created.
2) Set man-db/auto-update to true and install man-db from -proposed. Check that /var/cache/man/index.db is created ("accessdb | head"). Install vim and check that it is updated ("whatis vim"). Edit /etc/apt/sources.list to point to the next release. Run apt-get dist-upgrade and check that everything works. (For lucid → precise I had to run "apt-get install apt" first.)
Everything looks good, so marking this as verification-done.
