I have 2 vps
1st one with virtualmin panel and it is fully configured for bulk emailing smtp (DNS, rDNS, SPF, DKIM etc have been done on it)

2nd one with just virtualmin panel (nothing else configured)

Now i want to backup 1st one
and want to restore it on 2nd one

I know i can do it using virtualmin backup and restore option

But my question is that the settings of 1st one vps will work on 2nd one vps

or what changes i have to made on 2nd vps after restore in order to configure
it properly.
