OPNsense 20.7 "Legendary Lion" has reached its end of life. As such +it will not receive any more updates, but the upgrade to the new 21.1 series is +seamless and can be performed right here from the GUI by unlocking it below.
+Another method is to import and reinstall using a new installation image, +which will retain your settings (selecting "Import Configuration"), then +reformat the disk and apply a clean system (selecting "Guided Installation").
+You can also upgrade via console / SSH by using option 12 from the menu by +typing "21.1" when prompted.
+Make sure to read the migration notes and adjust for possible minor breaking +changes.
+Please backup your configuration, preview the new version via live image or +in a virtual machine. Create snapshots. If all else fails, report back +in the forums for +assistance.
