"Live" Migrate disk from one provider to another

[eugenevdm]

Hi, need help with the following:

Ubuntu 18.04 Server at Provider #1. The Old Provider. I am migrating all my VMs away from this provider to Provider #2. The New Provider running Proxmox.

At Provider #1, I have no access to the Hypervisor / VM Host. I only have a running Ubuntu 18.04 machine, that's not mission critical. Preferably I want to "bitwise" copy this VM to Provider #2 as I don't feel like re-installing everything, especially the configuration. I don't know what technology Provider #1 is using, but I am guessing Virtualizor, yet no access.

I have full control at Provider #2, it's my Proxmox box and I can do what I want.

So in my naivety, and as a noob, is this possible? I know about "live migration" and "high availability" which allows automatic failover or manual changes from one host to another. But I want to copy the disk. I can down the Ubuntu server so that's not an issue, but I don't see how this is going to help because I can't access the host to copy the VM file, put in on a USB, etc.

Maybe some kind of mirroring thing? Or RSync, god forbid. Please advise.

If you can boot from a live ISO / CD on the old host, you can do all sorts of things. For example use dd to send a copy of the VMs disk via SSH to the new VM / Proxmox host.
