First of all, Maestro and regular Gateway are not the same. and it depends of each deployment. Maestro use VMAC on same site. Also you have the possibility to have dual site, where each site have their own MAC.
Also is single object on management and not Cluster. You need to check as well fwkern file in case you already have on old device and make sure if applies on maestro.
At other hand we have the connectivity through uplinks.
If you are not familiar I encourage recommend to reach your local SE to engage Professional Services.
