Hope this may clarify some of your queries.
Although legacy Cisco Meraki products typically can connect to our cloud-based management software for the entire useful life of the product, following the EOST Date, some things may change, including the following:
- Cisco Meraki cannot guarantee that legacy hardware products will be able to connect to the management software indefinitely following the EOST Date;
- Cisco Meraki Technical Support may no longer troubleshoot the legacy hardware products;
- Cisco Meraki may no longer issue firmware updates or patches for the legacy products; and
- New software features available for the management software may not be compatible with the legacy hardware functionality or with the firmware running on the legacy hardware.
If either of the first two situations above occurs, then we will use our best efforts to provide the customer with a workable solution for upgrading from the legacy hardware and, failing that, will credit the value of any remaining license time attributable to the legacy hardware to the customer’s Dashboard organization on a prorated basis.
