move odoo + db + nginx from VPS 1 To VPS 2

VPS1:
Odoo is on production server working on ubuntu 20.04 (webmin+nginx+postgres) so I want to move it to

VPS 2:
this server working under proxmox debian 11 I want to install
Container 1: odoo
Container 2: nginx proxy manager

So I need :

- configure all of theses setup with proxmox under local network Vmbr1
