Difference in the versions between Edge and DevPortal to run

[#1]

Could anyone answer to the following question?

We plan to upgrade both Edge and Developer Portal to latest version on our private cloud.

My concern is that which product's upgrade should be done before another one.

Is it possible to Developer Portal whose version is 4.15.07.03 to communicate with Edge upper 4.16.01 version?

Or, Developer Portal should be upgraded to latest 4.16.X in prior to Edge?

Thanks,
Toshi
