1. Perform a backup
a) Head over to http://your-device42-IP-or-FQDN:4242 and take a backup before doing the upgrade. If you want to include users and settings, check "Backup Meta Data" as well; otherwise, leave the default.
Optionally, you can (also) take a virtual machine snapshot from your virtualization platform.
The default username and password for the Appliance manager is [ d42admin / default ] if they were not already changed; Please, however, ensure you change these to your own secure credentials!
