Yes, it's correct.

I can't because remote-migration returns an error (I cannot specify vlan tag on that bridge)

Can I send you in private ? Because is full of customer's names :/ 

But, this is a part of files:

==> /etc/pve/sdn/zones.cfg <==
vlan: ZonaVLAN
        bridge vmbr0
        ipam pve

qinq: VPVT
        bridge vmbr0
        tag 929
        ipam pve
        vlan-protocol 802.1q

==> /etc/pve/sdn/vnets.cfg <==
vnet: test100
        zone FWHous
        alias Vlan 100 Test 921 qinq
        tag 100

vnet: vlan902
        zone ZonaVLAN
        alias Vlan 902 Private-Vlan
        tag 902

qm remote-migrate 4980 4980 'host=,apitoken=PVEAPIToken=root at pam!remotemigrate=hiddensecret,fingerprint=hiddenfingerprint' --target-bridge vlan902 --target-storage NfsMirror --online

Thank you in advance, Fabrizio
