Upgrade or Downgrade Workflow
The software is available on cisco.com at https://software.cisco.com/download/home/286323307.
Each software release has release notes available here:
collaboration-endpoints/ip-dect-6800-series-multiplatform-firmware/products-release-notes-list.html.
The software from the release is loaded onto a TFTP, HTTP, or HTTPS server. You upgrade or downgrade
the base station first, then upgrade or downgrade the handsets. After the base station upgrades or downgrades,
it automatically reboots. After the handsets upgrades or downgrades, they automatically reboot.
Upgrade or Downgrade Workflow
The following workflow describes the steps you take to prepare the TFTP, HTTP, or HTTPS server and
upgrade or downgrade the system. Some steps you typically only do once, during the initial setup.
Note
We recommend that you upgrade or downgrade the base station first, then upgrade or downgrade the handsets
after the base station upgrade completes.
Before you begin
You need to have a TFTP, HTTP, or HTTPS server available.
