********************************************************************
What does this mean to you?
This means that AMP 7.7 will not allow upgrades if your OS is not CentOS 6 / RHEL 6 or higher.
How do I check my OS?
You can check your current OS by viewing the redhat-release file:
# cat /etc/redhat-release
This is also aliased as 'crr' if you're using the default AMP bash file.
What should I do if I'm still on CentOS 5 / RHEL 5 or lower?
The main steps: Upgrade to latest release that supports the OS version (If you haven't kept up on upgrades, you may need to do several upgrade steps, see http://kb.airwave.com/?sid=50140000000Mf7D), create a backup of the upgraded data, pull the backup off server, reinstall off the latest 7.6 ISO, restore the backup.
Step by step details:
1. Upgrade to latest AMP version: # start_amp_upgrade -v 7.6.1 (as of 2013-Jan-08)
2. Create a backup: # amp_backup
3. SCP or FTP the databackup.tar.gz in /alternative to another server or file storage (to be safe, also grab backups from /var/airwave-backup)
4. Follow quick install guide to fresh install off of the latest AMP ISO, version number needs to match step 1.
5. SCP or FTP the databackup.tar.gz back onto AMP in /var/airwave-backup
6. Restore the backup: # amp_restore -d /var/airwave-backup/databackup.tar.gz
7. Check OS: # cat /etc/redhat-release (# crr)
