Hello everyone, I am planning to upgrade my asterisk 1.2 to asterisk 1.4 to have asterisk gui, and my concern is, if my asterisk 1.2 dialplan will work on asterisk 1.4? And also all of asterisk 1.2 commands are compatible for asterisk 1.4? If I setup my asterisk 1.4 dialplan, is it same also in asterisk 1.2? Thank you so much guys… I really love asterisk and I wan to have a nice GUI…
Hi How many ways can you ask the same question 
You need to read the release not and upgrade notes. I would guess that your dialplan will need amending to work. a few functions have now gone.
