Migration from Vmware to proxmox

[chama.medhioub]

I have a large number of VMs to migrate from VMware to Proxmox. I used the Proxmox import wizard, but I'm encountering a problem where all the VMs get stuck at the boot stage and won't start. I've also tried converting the VMDK disks to QCOW2 format, but the issue persists. I've experimented with different controller types, and disk including IDE and SATA, but the VMs still won't boot. i have also used a backup/restore process.
Any recommendation please

If there are a lot of virtual machines to migrate, would it be better to use third-party software? Like Vinchin or Veeam?
