Hello all I'm just wating some guidence on upgrading my server. Currently I run a stand alone Debian Stretch server Linux mx 4.9.0-13-amd64 #1 SMP Debian 4.9.228-1 (2020-07-05) x86_64 GNU/Linux No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 9.13 (stretch) Release: 9.13 Codename: stretch ISPConfig 3.1.15p3 I'm wanting to change the server to operate as a VPS as the hardware has 32 CPUs and 48G RAM, so it has the resources. How would I best perform this upgrade given that I believe the migration tool has the limitation of staying within the same OS versions? So I can't migrate from a stretch server to a buster server. Your comments would be most helpful. Regards Fred
As Florian mentioned, there is no such limitation. You can even migrate to a different Linux Distribution by using the Migration Tool.
Seems you do not specify what kind of upgrade is this about. You mention so if you want something like Proxmox https://proxmox.com/en/proxmox-ve on that host to then create virtual machine for your ISPConfig host, that can be done. I would take a disk image of the current host, then import that to Proxmox and create a virtual machine from that. This is a bit complicated and causes a long downtime, so if you have only that one server computer that may be a problem. It would be better if this could be tested and practised so it goes smootly when doing it for real.
