After upgrading the controllers from 4.2.61 to 5.2.157 (with intermediate 4.2.176 upgrade) I was not able to change the name, or any other parameters of a newly joined 1242 LWAPP. There were no error messages, it just didn't work. I finally fixed it by creating global AP username and passwords. This is a new feature to the 5.x series of controller software. Are there any other issues like this I should be aware of, when upgrading from 4.2 to 5.2?
