I'm new to IP Office 500 and not too knowledgeable on the older releases. I have a customer with an IP Office 500 4.2(4) and I need to go to R8 essential with SIP, I'm not sure what mode it's running. Please help..
Can I use the 202959 IPO LIC IP500 IPO STD UPG TO PRO then 267792 IPO LIC UPG R8.0 or can I jump straight to the upgrade to R8 by using the 267792 only?
Do I need to add the 267786 IPO R8+ ESSNTL EDITION+ LIC also?
Would any hardware Smartcard/SD feature key or control unit need to be replaced?
Can I move to R7 then R8 by using the 262644 IPO LIC UPG R7.0 then the 267792?
