I have a setup with a hub and about 25 spoke site (Auto-VPN). On the hub site i use a MX84, for the spoke
site I use MX 67.
Now I need to upgrade one spoke site to the stable rel. candidate version (15.52), because of a needed function.
All the other MX's will stay on 14.53.
Now, does anyone have experience with a setup where not all the sites do not have the same version?
Interested in if VPN will work fine, any potential problems...
