I have a few virtual machines currently on ESXi that I need to move to my Proxmox server. These VMs are large, having multiple virtual disks, some of which are 2TB. The migration tool seems to be capped at 1Gbps, so migrating with the migration tool isn' really possible without incurring significant downtime. Is there an established best practice/workaround for moving large VMs from ESXi to Proxmox?
