Actually, db_upgrade is not relevant in this scenario.

The relevant section of the BDB manual is:

If the application has a Berkeley DB transactional environment, and the log
files need upgrading but the databases do not, the application may be
installed in the field using the following steps:

  1.. Shut down the old version of the application.
  2.. Run recovery on the database environment using the DB_ENV->open method
or the db_recover utility.
  3.. Remove any Berkeley DB environment using the DB_ENV->remove method or
an appropriate system utility.
  4.. Archive the database environment for catastrophic recovery. See
Archival procedures for more information.
  5.. Recompile and install the new version of the application.
  6.. Restart the application.
