For reasons too long-winded to go into here I'd like to attempt to migrate an existing Debian Jessie LAMP server to a Proxmox VM 'in place'. My plan is to install Proxmox on the same machine as the existing LAMP stack, then to migrate the server into a VM by stopping services, copying the filesystem, and following the well-documented procedures to get that filesystem working in a VM. Then, in theory, I can point the server's primary IP to that VM and - abracadabra - to the outside world it seems like it's the same system and no one knows any better (except for any downtime).
Now, this is where you're going to tear my plan to pieces.
I've trialled the Proxmox VE 5.0 distro on a server to get a feel for it and plan out how my VMs will work, understand that network model etc. I'm quite comfortable with Proxmox (the n00b question on networking I'm about to post in a sister forum notwithstanding).
If I install the proxmox-ve and other dependencies on this production server I like to think that I'll then have the same functioning server, but with the Proxmox GUI on port 8006 and the ability to create VMs on the existing disk partitions. Is this correct? Or am I completely mistaken and the Proxmox install will trash everything and/or do something destructive to the file system/kernel?
Any help appreciated! I tried searching for installation on production/existing systems but didn't see any similar posts.
