best way to move websites to new server

Hi,
I want to create a fresh install of my ispconfig server, there 12 web sites on the server and i need to move them to new server, so what is the best way to move websites to new server instead of backup files and databases one by one.

 

thanks till, one quick question my server's name is tlsteknoloji.net (ns1.server1.tlsteknloji.net) can i host tlsteknoloji.net website on this server? because when i forward dns to my ip address all sites working except tlsteknoloji.net, when i try with changing hostfile of my os even i'm getting "DNS_PROBE_FINISHED_NXDOMAIN" for this domain only.

 

Is this on the new server or old?
It seems DNS is not working for tlsteknoloji.net

Code:

$ host tlsteknoloji.net
;; connection timed out; no servers could be reached

These are the name servers for that domain:

Code:

$ whois  tlsteknoloji.net  | grep "Name Server"
   Name Server: ATHENA.TLSTEKNOLOJI.NET
   Name Server: KRONOS.TLSTEKNOLOJI.NET
Name Server:KRONOS.TLSTEKNOLOJI.NET
Name Server:ATHENA.TLSTEKNOLOJI.NET

 

you are correct when i check ns records it show the same thing but when i create record on my host file and try it returns DNS error, that confuses me

 

attached host file configuration on my previous post on my client pc not on server, correct me if i'm wrong but when i added that record i should be able to reach to website on ispconfig server even if don't do any dns forwarding right?

 

that was the problem exactly, edited host file as www.tlsteknoloji.net and i can reach now, thanks.
