Asterisk Upgradation

Hi all,

Currently I am using asterisk 1.4.19 , Since it is bit old I am planning to upgrade it to 1.4.39 which is the latest 1.4 release.
What is my concern is I don’t want to change the config files. I need the exact dialplans and configs in 1.4.19 on 1.4.39 so is it possible to use the same config files in 1.4.39 ??. I also have hardware card TE122 for PRI calls. Zaptel is it’s driver. But now zaptel is updated to DAHDI. So will asterisk 1.4.39 will support Zaptel , because i don’t want to recompile driver to DAHDI, actually I am afraid to do it. Please give me some leads… Thanks in advance.

It should be possible, providing that you are not relying on any bugs.
