Asterisk 1.6.1 to asterisk 1.4.17

Hi how to downgrade asterisk 1.6.1 to Asterisk 1.4.17.
I need to install asterisk 1.4.17 and I have already 1.6.1 on fedora core 8. The mysql and add-ons have to install to.
Thank´s for your support

Why? If you want a 1.4 version, use a supported one, like 1.4.30.


  • save the configuration;
  • save the relevant UPGRADE files and Change files;
  • delete the code and libraries;
  • install the older version, without configuration files;
  • use the UPGRADE and Change files to work out how to rollback the configuration files.
