[Pdns-users] Migrate from one backend to another

[Lucas Rolff]

Hello,

I'm currently running a PowerDNS setup where I have a hidden primary as well as multiple secondaries (spread across multiple countries and datacenters) - I use MariaDB as a backend, and all replication is currently done via AXFR.
Roughly 30% of the domains use DNSSEC.

I'm planning on migrating to lmdb eventually as the lightning-stream feature becomes available, and then use an S3 backend instead.

However, this obviously means migrating the backends to use lmdb.

Do anyone have any tips/tricks on how to perform this migration with relatively low impact? I can block writes to the hidden primary without a problem for multiple hours.

Thank you in advance!

Best Regards,
Lucas Rolf
