Although under the hood a lot has changed in OpenDNSSEC 2.0, the architecture and workflow has more in common with OpenDNSSEC 1.4 than it differs. This 'HOWTO' will initially focus on procedures that have changed or are formerly not possible. In the future this should be more complete and include updated sections now only find in the 1.4 Documentation.
Upgrade OpenDNSSEC 1.4.9 to OpenDNSSEC 2.0
With the rewrite of the ods-enforcerd daemon the database layout has changed as well. Upgrade scripts for Sqlite3 and MySQL are provided in the source tarball in enforcer/utils/1.4-2.0_db_convert. The text file README.md in that directory explains the process. Note: while 1.4 supplied scripts to convert from one database backend to the other, 2.0 does not have these yet. If you are planning to change database backend do that first before upgrading OpenDNSSEC.
