Re: [webmin-l] [UPDATE 1] How do I migrate my slave DNS server from CentOS 7.9 to Rocky Linux 9.1?

[Przemysław O. <prz...@ma...>]

Hi

Assuming this is a slave DNS for single virtualmin server I should just 
install new slave DNS and then add it to virtualmin as usual with the 
option to copy all existing zones.

Its also possible to do it when single slave DNS is used for many 
masters under the condition that there are no overlapping domains on 
different masters.

Even if your slave DNS is out for several hours it should have 
practically zero impact for clients

Your primary must remain operational and there is the problem of 
delegating domains if there is only single DNS (it might be impossible 
to delegate new zone to a single DNS server)

The master should populate the slave within minutes after its added in 
virtualmin as a slave.

Regards
