I have a rented server which is going offline at the end of the month and i need to migrate it to a new server, I've searched the forums but at the moment it doesn't seem to be an easy way to upgrade / migrate a version this old of i-MSCP.
My system is an Ubuntu 16.04 with i-MSCP version 1.1.21 Build: 20141230 Codename: Eagle and I want to migrate it to a brand new Ubuntu 18.04 with the latest i-MSCP 1.5.3.
The problem is that i currently have 46 Domains, 8 Subdomains, 3045 e-mail accounts , 38 FTP accounts, 45 sql databases, migrating them manually like I did on a previous server this old which only had 6 domains would be a nightmare. (took me 4/5 hours to manually move the previous one)
My question is : Does anyone know an easier way to make the upgrade ? Maybe a script to update the SQL databases to the latest format ? From what I could tell, if the SQL is ok, i could just install from scratch the latest version.
The server is a production server so a larger than 1h downtime would be a problem.
I would like to be able to upgrade the current server to Ubuntu 18.04, than upgrade the i-MSCP to 1.5.3 so when it's time to move I won't have any surprises.
Any ideas are welcomed.
