Virtualmin and Webmin full backup/migration

I never did this with Wmin/Vmin so i would like to ask if is possible to make full backup of both and then move to another server. Important part is i made several changes manually with postfix, bind (using dnssec), apache, mariadb… so i would like to know if i do full backup from Wmin will pickup all changes.
Last but not least, is there SSH commands what could be used to do this job?

I need to know all this info because if there is smallest chance that Wmin cant pickup all the changes then i will need to do all manually rather than losing several months of testing.

P.S. I know you have a link where is explained how to migrate but doesnt answer to all my questions especially one about system settings as i dont care too much about virtual servers/domains as they are just for testing.


Unfortunately, there isn’t an automated way for migrating config files in /etc.

Virtualmin doesn’t handle that for you, as it’s often not possible to move the full config file from one version of a distribution to another.

Is your new server running the same distribution/version as the old one?


Yes, only difference would be the amount of memory and changing from hdd to ssd but i think to bring back all what i already have. OS: Centos 7.
I’m asking because this is testing server i had with Vmin and i spent insane amount of time to fine tune many things thats why i was asking if Wmin supports full migration. Another option would be to install all the same and then copy the changes from /etc to the new server. It would be good if i could do at least full Wmin/Vmin backup of settings as virtual servers/domains are really not important and i’m using it only for testing (no value at all).
