Migrating VM from VMware to Proxmox and retaining network config

[squeezerie]

Hello Everyone,
Is there a reliable method to import virtual machines (VMs) from VMware to Proxmox VE while retaining the network settings after attaching the disk? I have tried several times, but each time I imported a VM, the network settings were not configured properly.

Make sure that the MAC address for the vNIC is the same if the VM gets its network config via DHCP.

Thank you for responding. I apologize for not mentioning earlier that I have already set up the MAC address and network model to vmxnet3. Additionally, I have assigned static IP addresses to the VMs. However, upon booting up, the network settings revert to "Auto-obtain". Is there a way to resolve this issue?

This is an issue inside the operating system of the VM. I do not think that Proxmox can do anything here.

If you are using static IPs, then its unlikely that you can easily transfer network settings in way that it just works.

If you are using Linux based OS the name of the interface depends on PCI bus and other parameters. They will most likely change in the new hypervisor and you will need to update your configuration.

If you are using Windows, the UUID of the interface will also change because the of the above and the fact the driver is not really identical, even if it has the same name. https://learn.microsoft.com/en-us/t...#:~:text=ID for Adapter-,Note,-ID for Adapter

Only with DHCP you may be able to receive the same reservation if, as mentioned above, you statically assign a custom MAC and your reservation is tied to the MAC.

Just wanna try to revive this thread. What I keep coming back to is people that are using either the VMware converter tool in the proxmox gui or the ofv import route, are reporting that the networking config remains intact after the process, so it appears that the abovementioned procedure has some way of preserving networking config and probably some other items/config/info along with it.

Used the VMWare Converter Tool (from hardware to VMWare) and the Proxmox ESXi Import Assistant quite a lot and i always had to fix the "network issues" in Windows (especially Server versions when they were DC, DHCP or DNS) manually.
There are scripts which may help you to fix the NLA things after "changing" the network device: https://learn.microsoft.com/en-us/a...rk-location-awareness-not-detecting-domain-ne
