I have a deployment, mesh style, of IAP275s and IAP277s. These radios are now End-of-Sale, though still supported until 2024. So now our clients want to expand this deployment and add a few more locations (its a water treatment facility) into the mix. Well, IAP270 series is no longer an option and the recommended replacement is the AP375. I have been told by a distributor/reseller that the AP375 is NOT compatible with the IAP270 series. I thought that as long as they have the same firmware rev, that they would join the cluster and then be able to mesh with the others.
Can anyone confirm/deny this for me? I really don't want to tell the client that they would have to replace the entire deployment that was only installed less than two years ago.
