We have 2 Meraki Org A & B that we are trying to merger together over a long period. Our Data Centre DC1A (using an MX100) in Org A has services that sites needs to access via VPN and not exposed to the Internet.
Our plan is to migrate site from Org A to Org B one by one (move hardware & licenses etc) and re-create the site over in Org B. Keeping down time to a minimal.
Sites from Org A will be recreated in Org B (lets call it network B1). However B1 still need to access DC1A until it is moved over at the end of migration phrase.
What is the best and simplest option "bridge" B1 with DC1A (still in the old Org). How would you do this? Can it be done with only Meraki HW / VMXs in Azure or needing additional hardware?
Thanks
