Migrating a KDC database

[Daniel Savard]

Is there a way to migrate a KDC database when upgrading from a minor
version number to another one? I know I am supposed to backup the
database, then upgrade Kerberos and finally restore the database. But,
since it appears I missed this procedure, I would like to know if
there is any tool to perform the same thing this procedure is doing?

I upgraded from 1.3.6 to 1.4.1.

TIA
