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 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.

Perform an non-scheduled key rollover

OpenDNSSEC can perform a key rollover at any time. It does not matter if another rollover is already happening.

ods-enforcer key rollover -z -t ZSK 

The next scheduled rollover (unless <ManualRollover/> set in the policy) for this key type will be offset from now. I.e the new key will be used for the full lifetime configured in the policy. Keys that are no longer desired are being phased out as soon as the policy tolerates and within the bounds of what are valid DNSSEC states. This means it is very well possible an already running rollover is never completed. Consequently if the lifetime of a key is very short, in the order of the TTL of the DNSKEY, it might be possible the Enforcer is never able to complete a rollover and the old key will be used indefinitely. This is considered a bad configuration.
