Migration to other server

Login to Your system via ssh and make a double backup of your databases:

  mkdir /root/backups
  cd /root/backups
  mysqldump --all-databases -uDATABASEUSER -pDATABASEPASSWORD >/root/backups/alldatabases.sql
  tar -czvf alldatabases_BACKUP.tar.gz /root/backups/*.sql

This will make an archived backup with your databases in /root/backups/alldatabases_BACKUP.tar.gz file

Leave one copy in some safe place like your workstation and second somewhere in server.

To extract files from archive do:

  tar xvfz file_name.tar.gz

Then copy required files like /etc/asterisk/h323.conf or /etc/asterisk/sip.conf or whole /etc/asterisk directory itself somewhere in the safe place. Copy all other files which You think can be important or usefull.

Thats it, proceed with Migration to other server.
