4.8.1 Upgrade/Downgrade Considerations
When upgrading or downgrading access point configurations between the 1.0.0.0-xx (or 1.0.1.0-xx)
and 1.1.0.0-xx baselines, the following should be taken into consideration as certain functionalities
may not be available to the user after an upgrade/downgrade:
• When downgrading from 1.1.1/1.1 to 1.0, the access point is configured to default values.
• After a downgrade from 1.1/1.1.0 to 1.0.x.x, WLANs mapped to LAN2 would still be usable,
but now only available on LAN1. Once upgraded back, those WLANs previously available on
LAN2 would still be mapped to LAN2.
• If downgraded to the 1.0.0.0-xx baseline, and a restore factory defaults function is
performed, only 1.0.0.0-xx default values are restored to their factory default values. The
feature set unique to 1.1/1.1.1 can only be restored to factory default when the access point
is running 1.1.0.0-xx firmware.
• An AP-5181 model access point does not support firmware prior to 1.1.1.0.
• Export either a CA or Self Certificate to a safe and secure location before upgrading or
downgrading your access point firmware. If the certificate is not saved, it will be discarded
CAUTION Prior to upgrading/downgrading the access point’s configuration,
ensure the access point’s current configuration has been exported to a
secure location. Having the configuration available is recommended in
case errors occur in the upgrade/downgrade process.
