We want to migrate our Debian 10 based Virtualmin server to a new server that will be Debian 11 based.
The question is if we can keep the old servers hostname and domain on the new server.
We wanted to use the Virtualmin move virtual server feature to migrate everything from the old server to the new server. But I don’t think it is possible to have two servers configured as the same hostname.domainname.com
Another question is about our secondary nameserver. Our old Virtualmin server has a slave DNS server setup in a different datacenter and we will want to keep that slave server but have it associated with the new Virtualmin server.
I don’t know if I’ve explained this well so if you need more info just let me know.
Just think this through. Hard to give specifics for each individual setup. Just give the new server a different name in DNS. Generally only the web servers care about the actual name. When done, change the DNS.
The old server is the primary name server and also hosts 40 virtual servers with users and email. I want to replace this server and make the new server the primary name server so I can de-commission the old server.
I was hoping to use the Virtualmin migrate virtual servers to the new server from the old server.
Hello @ID10T@calport@tpnsolutions@Gomez_Adams and all and thanks for the tips.
I have migrated the virtual servers (40) to the new server and only had a couple PHP extension issues to sort out on the new server. All seems to be working with the only exception I can see is the slave DNS server is getting zones but no records.
Not sure if you mean on the master DNS (new server) or the slave DNS server. Where is this create master zones option? I’m presuming is it because there are master zones on the master DNS (new server) and on the slave DNS server the zones appear as slave - just all zero records.
I wanted to shout out to the Virtualmin team for making the “Transfer Virtual Server” feature! This server migration went a hell of a lot better than I have experienced with other systems or by manually downloading and uploading files and backups!
