As a general precaution, always backup your configuration file (using the backup/restore facility in the webGUI) before attempting a firmware upgrade.

Upgrading to 1.23 from 1.22 should be possible without any specific configuration changes.

When upgrading from 1.2 to 1.21, if you're using the captive portal, make sure that your login form contains the "redirurl" hidden field (even if you're only using HTTP), otherwise it won't work anymore!

Upgrading from 1.11 to 1.2 is possible without having to do any modifications to the configuration – the behavior should be the same (but make sure to check the detailed change log for information on subtle changes/fixes that may affect your setup!).
