We currently have 3 MR-18 APs. We will soon be adding 3 MX devices, 3 switches and at least 1 more AP (MR-42) possibly 4 (3 to replace our MR-18s).
Our 3 APs have close to 2 years of licensing left on them and all of the new equipment will be purchased with 5 Year licensing. If we want to replace 2 or possibly all 3 of our MR-18s with the newer MR-42s, how would we do that and not lose the 2 years of licensing left on the 3 MR-18s we currently have?
I understand the co-termination thing but things seem too get muddy when adding new equipment and removing older things. What is the best way to upgrade the MR-18s to MR42s and still keep the 2 years of licensing left on the MR-18s we would likely be getting rid of?
