I'm looking to upgrade 2 3020 concentrators to the newest/stable software revision. I'm seeing 4.1.x and 4.7.x versions available, with both being updated at approx the same time. ( ) One of my concentrators has 4.1.x code and the other has 4.7. Is there and upgrade path, or can I just upgrade to two of them to the newest 4.7.x????
4.7 has been out for a long time. I have experience problem with the latest version of 4.7. There was a bug in the AAA and clients were not able to authenticate after a while(2-3 hours).
Be careful if you decide to put the latest.
