MX Firmware 16.x and 17.x compatibility between different MX devices

[Ignacio995]

We have 2 MX400, VPN concentrators, in our Datacenter, and by Meraki documentation the last MX supported version in these devices is MX 16.16.6.



And we have MX65 devices in our remote sites, that they do support the last MX version MX 17.x.



So, the question is:

Is any compatibility issue between MX 16.16 and MX 17.x? I mean, can we upgrade the MX 65 (VPN spokes) devices to MX17.x considering that MX400 (VPN HUB) are in MX16.16?

Thanks and regards.

Yes, this will work. I also typically update the hubs last and my spokes were running v17 while one or more hubs were still on v16.

We do the same, we went 17.x on the remote sites before ending up with the hub done last.

Yup, same here.
