====== Upgrade from 0.4.x ======

FIXME Only a draft version, must be enhanced, corrected.

Please read [[http://astlinux.svn.sourceforge.net/viewvc/astlinux/branches/0.7/UPGRADE.txt|UPGRADE.txt]], [[changes-0.6]] and [[changes-0.7]] before you start.\\ If you are using mISDN with PCI cards please also read **[[misdn|this]]**.

Because there wasn't a WebGUI backup function in the 0.4.x releases, you could backup the content of your keydisk (''/mnt/kd'') over SSH:

  cd /mnt; tar cf - kd | ssh user@hostpc "cat >Astlinux_KD.tar"
  
Then you are recommended to start fresh with a new [[new-install|Installation]].

Remember in the 0.4.x versions Asterisk 1.2.x was used and now in Astlinux 0.7 Asterisk 1.4.x (starting with 1.4.28) is used -- and a lot has changed. There is also a newer Linux version (2.6.27.29) in 0.7 and many more structural changes. Re-using your old keydisk files from 0.4.x could therefore cause a lot of trouble. 

It is therefore recommended manually to go through your configuration files from /mnt/kd, making any changes required to reflect the new kernel and Asterisk versions.
