Hi,
Airwave backs up everything during the nightly maintenance. The data backup file contains all of the device and group information as well as historical data and system files, including IP address, NTP information, mail relay hosts, and other AMP settings. This will also include the Visualrf backup.
When we are swapping from old server to new one, download the latest nightly backup file to your PC. Do a fresh install of same Airwave version on new server(i.e if old server is on 8.0.11, make sure the new server is also on 8.0.11 for restoring the backup), copy the nightly backup and restore it. Make a copy of license. Once the new server is up we can safely shutdown the old server using the below command from CLI,
# shutdown -h now
Let me know if you have any further queries.
Regards,
Vishnu
