i have a perfetcly running asterisk ver 1.0.9 with some modifications in the code and alot in conf files
now i am about to upgrade it to a newer ver i.e 1.2.11, soo what i need to do to make sure everything runs perfectly same as on the older version
conf file is’nt a major issue becuase they can copied into the new asterisk, the real problem is when ill upgrade will the customization i did with the core source files needs to be re-modified or when ill upgrade it wont have any effects on the modifications and everything will run perfectly same as before ???
