Hi Chris, I'm not able to guess what went wrong with your once-before attempt. No need to freeze zones before server shutdown. Zone freeze is there for some cases you want to avoid shutting down a server. I confirm that you can shutdown the server and move all the metadata (zone files, journal, KASP db, timer db) and configuration to another server. Obviously, if you are moving a master server, you need to adjust the configuration on slaves, so that they accept the new master. However, merging two servers (each running some zones) is more difficult, as you would need to merge all the databases (journal, KASP db, timer db). This operation is not supported. You might try following: 1) shutdown both servers 2) backup both data 3) merge each database along the lines of https://www.knot-dns.cz/docs/2.9/singlehtml/index.html#export-import-kasp-db 4) copy zone files, .pem files, merge config file manually, ... You might sacrifice timers and/or journal, depending on features you use / your configuration. BR, Libor Dne 03.05.20 v 11:08 Chris napsal(a):
