Hi there,
I want to upgrade my Ubuntu Server (from 10.04 to 12.04).
Because upgrading os made my system useless in the past I want to do it by setting up a new server and transfering all information to the new one.
Is there a easy way to transfer all information and data?
ISPCP has a backup and restore script that backup almost everything (except mails grrrrrr) - is there something similar for i-mscp?
I too am interested in this topic, my I-MSCP is installed on a VPS, but I want to migrate everything to another VPS Provedor more powerful, as you could make?
There are some threads in the Migration section of the forum with good information about migrating to a different server. It depends if you're keeping the same hostname and IP, or changing them, what will happen.
It basically involves taking a mysqldump, and copying of all /var/www/virtual/ files and /var/mail/ files.
Make the new server, install same i-mscp version and configuration. Stop i-mscp_daemon.
You take the mysqldump from the old server, and import it to the new server (backup the new server first, you need the debian-sys-maint password entry). Set all domains statuses to "change". If you changed the IP address or hostname, change those in the database as well.
Start i-mscp daemon, it should start creating all the domain directories, etc.
Make sure /etc/groups has all the right users and all the /var/www/virtual directories are there, then copy over all those /var/www/virtual files and /var/www/virtual files.
That's kind of a basic overview, there are a lot of things that can go wrong, or it could go smoothly, it depends on if you have custom configurations, etc.
something more to improve a transfer with minimum change, dns zones and statistical data of user visits
