hello sorry for this title which may sounds wrong…my question is simple: like i believe every single wowza user, we are constantly adding and upgrading servers…for example i wan’t to change a previous server, using the same wowza key…so the process is: i setup my news server i shutdown the old when everything is fine i set the key of the previous to the new server i start the new server the thing is everytime, u need to get a new dev key…not a big deal, but between updates,upgrades, maintenance and everything, maintaining stream servers network is a lot of work…could be easier without these dev key issues…or maybe i missed something 😃 in this case please tell me what, otherwise, thank you for paying attention to this message cheers !

Hi, I’m not sure I clearly understand, but I think you are saying you use a dev key to initially setup the new server? Development keys do have an expiration date/time, and you are not supposed to use the same key at the same time in multiple installs. Are those mainly the restrictions you are concerned about? Daren
