I've done it in the past, I thought it was as simple as putting the correct bin files in my manager directory. I am wanting to upgrade my 9508 from .45 to .55 (or later if there is a newer version). I am running Manager 10.1, I have a single PC that has Manager and VMPro on it. In Manger > System, I have TFTP, HTTP and MANAGER IP's all pointed to my manager PC. I am unsure of what else needs to be done, can someone help?
