Migrate VMware-VM to Proxmox

Hello all,
I would like to migrate the VMs from VMware Workstation to Proxmox. Currently a WIN10.
As a basis for the procedure I have taken generally known information source:
https://pve.proxmox.com/wiki/Migration_of_servers_to_Proxmox_VE#VMware ( Virtual-to-Virtual (V2V)).
The first step is to export the VM into an ".ovf". In VMware Workstation -> File -> Export to OVF.
After some time, however, not only one ".ovf" is exported, but several files:

In the next step, all exported files are transferred to the Proxmox server - according to the description above.
The VM can also start successfully. Unfortunately when starting it always comes the:

"WARN: no efidisk configured! Using temporary efivars disk. TASK WARNINGS: 1".

Maybe there is a solution to this. Thank you!
I do it the old-school way and copy over the vmdk (metadata) and vmdk-flat (data) files and use "qemu-img convert" on the new host to convert them to raw format.

I did this when I migrated from ESXi to Proxmox.

Plenty of videos and blogs on how to do this.
use "qemu-img convert" on the new host to convert them to raw format.
Take a look at the qm disk import command (man page). This way you can point it to the source image and specify the target VM and storage. Converting the disk image to the correct format is done on the fly.
