VLANS

If any VLANs were in use directly on the interfaces involved, migrate them as follows:

• Add new VLAN tags using the LAGG interface as the parent (Interfaces > Assignments, VLAN tab)
• Fix the assignments to use the LAGG versions of the tags (Interfaces > Assignments)
• Remove the old tags from the physical interface(s) (Interfaces > Assignments, VLAN tab)

Do not edit the existing tags and change the parent interface, it will cause problems with the interface assignments. Always create new tags, switch the assignments, then remove the old tags.
