when making a comparison. Change the last two characters to update the access point's
configuration. The two characters can be alpha-numeric.
Upgrading from a legacy to a new firmware version is a two step process requiring the same upgrade
procedure to be repeated twice. The first upgrade will result in a bootloader change, and the second

Upgrading to a new access point firmware baseline does not retain the configuration of the previous
(lower version) firmware. Motorola recommends users export their 1.0 configuration for backup
purposes prior to upgrading.

using the automatic download feature. The automatic feature allows
the user to download the configuration file at the same time, but since
the firmware reverts to the default settings of the lower version, the
configuration file is ignored.
