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 to 1.0, the access point is configured to default values.
• After a downgrade from 1.1.0.0-XX to 1.0.0.0-XX, WLANs mapped to LAN2 would still be
usable, but now only available on LAN1. Once upgraded back to 1.1.0.0-XX, 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 1.1.0.0-XX can only be restored to factory default when the access
point is running 1.1.0.0-XX firmware.
• 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
and not available to the user after the upgrade or downgrade. If discarded, a new certificate
request would be required.
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.
NOTE For a discussion on the implications of replacing an existing Symbol
AP-4131 deployment with an AP-5131 or AP-5181, see
Replacing an AP-4131 with an AP-5131 or AP-5181 on page B-18.
