Mutiple VLAN's over unifi site magic

Hi gang,

I haven't used unifi site magic before, but it looks like a wonderful product and I use unifi currently just as a controller of the wifi essentially at each of my sites (1 controller shared across our entire WAN, with different sites setup for each site) and I'm looking to use unifi to take over and control/route our SD-WAN, ditch the ISP based WAN, ditch the expensive tedious to setup cisco routers and ditch the palo alto VPN setup we use, possibly using unifi USG ultra's at each site.

I also use a USG Ultra at home as my home router with 4 AP's and am in love with its ease of use and I am pretty confident in the console configuration for most things.

all of our sites are currently connected with an MPLS network in australia and 1 site that connects via an ipsec tunnel to the USA, as well as VPN services from the ISP, the plan is to ditch these more expensive connections and lack of transparency with our ISP and just get faster connections of varying different kinds in each site and do away with the ISP managing the WAN, and run the client VPN services through the unifi equipment as well.

Each of our sites operates several VLAN's that are all connected to the same VLAN's at each site VIA the MPLS WAN.

(these are made up VLAN's not the actual names/ID's to make the point)

"IoT" VLAN (5) in site 1 flows through to multiple sites as the same VLAN
"Internal" VLAN (10) in site 1 flows through to multiple sites as the same VLAN
"Dev" VLAN (20) in site 1 flows through to multiple sites as the same VLAN

"Server" VLAN (30) in site 1 flows through to multiple sites as the same VLAN

I've seen a few site magic tutorials and videos and I feel fairly confident I can make this happen easily enough, but so far none of them have covered setting up site magic where you want to connect more than just 1 vlan to the same vlan at a different site and I wanted to make sure this was possible before I dig deeper into this adventure.

Does anyone have experience with doing this particular task?
