This article explains how offsite VLANs are created and goes over some limitations and best practices associated with them.

You can only create VLANs while setting up an offsite virtualization, as they will be created on the server for the VM. This server will then be the "Master Server" for the VLAN and will share the VLAN as needed. Only one VLAN with a given IP scheme can exist on a master server (For example, if a VLAN with the subnet 192.168.2.0/24 already exists and is in use, you will be unable to create it, and must either select a different networking scheme or reach out to Datto Technical Support for assistance).
Remove the old VLANs after your Disaster Recovery or DR test scenario completes. Remove the old VLANs after your Disaster Recovery or DR test scenario completes; doing so helps keep those subnets available when needed. Otherwise, unless your virtualization occurred on a private node, multiple devices from multiple partners will sync and potentially virtualize on the given offsite server. Removal of inactive VLANs ensures that commonly used subnets (such as 192.168.1.0/24 and 10.1.1.0/24) will remain available.
