[BlueOnyx:27012] Re: Exporting and Importing Secondary Mail Server Records

[Richard Morgan]

Thank you for the detailed answer, but it's not DNS but secondary email services I'm having trouble exporting. 

I can see the records I need in /etc/mail/mailertable but I don't know how to move them in a way that makes them editable in the GUI.

Many thanks, Richard

Yeah, Easy-Migrate has an option to migrate DNS. Which includes 2ndary DNS, too:

https://www.blueonyx.it/easy-migrate

The command to migrate just DNS would be similar to this:

/usr/sausalito/sbin/easy-migrate.pl --source <IP-of-Source-Server> -p 22 --dnsonly

As for outdated SSH ciphers? The work around for that is explained on the Easy-Migrate page linked above:

---------------------------------------------------------------------------
5211R (EL9) uses a more modern SSH and some older ciphers have been deprecated. This is no issue if you're trying to import from BlueOnyx 5210R or BlueOnyx 5209R. But if you still have a BlueOnyx 5207R or 5208R and want to Easy-Migrate straight to BlueOnyx 5211R? In that case you need to create the file /root/.ssh/config on your BlueOnyx 5211R and add the following text into it to allow user "root" to use older HostKeyAlgorithms and key-types:

HostKeyAlgorithms +ssh-rsa,ssh-dss
PubkeyAcceptedKeyTypes +ssh-rsa,ssh-dss
---------------------------------------------------------------------------

Other than that? There are some old scripts on each BlueOnyx that allow you to export/import just the slave-zones:

Export DNS-Slave zones: /usr/sausalito/sbin/dns-slavezones.pl

That dumps the zones on the screen. Copy and paste them to the new server where you want to import. Save the dump there as /usr/sausalito/sbin/slaves.txt

Then run this script /usr/sausalito/sbin/dns-import-slavezones.pl and it ought to import it.
