====== Asterisk PBX Migration ======

  - Get to a Linux console on the old Asterisk box
  - Log in as root
  - Archive the Asterisk configuration files
    * ''tar -zcvf etcasterisk.tgz /etc/asterisk''
  - Archive the Asterisk sound files
    * ''tar -zcvf sounds.tgz /var/lib/asterisk/sounds''
  - Archive the Asterisk voicemail files
    * ''tar -zcvf voicemails.tgz /var/spool/asterisk/voicemail''
  - Archive the provisioning files if they exist
    * ''tar -zcvf tftpboot.tgz /tftpboot''
    * These files are in '/home/PlcmSpIp' on Thirdlane
  - Archive the DAHDI configuration files if you have a TDM card
    * ''tar -zcvf etcdahdi.tgz /etc/dahdi''

This will create files that can be transferred to the new PBX.

<file>
scp {etcasterisk.tgz,sounds.tgz,voicemails.tgz,tftpboot.tgz,etcdahdi.tgz} root@new.pbx.server:/
</file>

This leaves the archives in the root of the new PBX.

Log into the new PBX as root and extract the archives.

<note warning>Think hard about extracting ''/etc/asterisk'' in its entirety to its original location.  It will probably break things.

At a minimum, create a backup of the existing files before extracting:

''cp -avr /etc/asterisk /etc/asterisk.bak''</note>

<file>
cd /
tar -xzvf sounds.tgz
rm sounds.tgz
tar -xzvf voicemails.tgz
rm voicemails.tgz
</file>

If you want to extract the files to a temporary location:

<file>
mkdir /root/asterisk_backup
mv etcasterisk.tgz /root/asterisk_backup
cd /root/asterisk_backup
tar -xzvf etcasterisk.tgz
</file>

Finally, a word about permissions.  You will want to check that the newly extracted files have appropriate permissions.  They may need to be adjusted to something similar to this:

<file>
chown -R asterisk.asterisk /var/lib/asterisk/sounds
chown -R asterisk.asterisk /var/spool/asterisk/voicemail
find /var/lib/asterisk/sounds -type d -exec chmod 775 {} \;
find /var/lib/asterisk/sounds -type f -exec chmod 664 {} \;
find /var/spool/asterisk/voicemail -type d -exec chmod 775 {} \;
find /var/spool/asterisk/voicemail -type f -exec chmod 664 {} \;
</file>

===== Sound Files =====

There are two sound file directory layouts in existence.  The new way has alternate languages in their own subdirectory of ''/var/lib/asterisk/sounds''.

If you see errors such as:

<file>
[2011-11-21 10:25:33] WARNING[9730]: file.c:665 ast_openstream_full: File digits/1 does not exist in any format
[2011-11-21 10:25:33] WARNING[9730]: file.c:992 ast_streamfile: Unable to open digits/1 (format 0x4 (ulaw)): No such file or directory
</file>

first check for the existence of the sound files and the permissions.  Then check this setting in ''/etc/asterisk/asterisk.conf'':

<file>
languageprefix=yes
</file>
