Best thing to do in my opinion:
1. take back-up of your existing server:
Run the backup script by typing 'amp_backup' on the Airwave CLI and copy it out of your server
This creates a backup of the system located in /alternative/databackup.tar.gz.
2.copy your license from the GUI
3.Install your airwave on your new server with the same IP address as the old one so you don't need to transfer your license and you don't need to adapt your controllers
4. copy your backup to the correct folder /alternative/databackup.tar.gz
5. do a restore of your data
amp_restore -d /alternative/databackup.tar.gz
(don't forget to add your license again on the new server)
If I am forgetting something, please complete :-)
