NCS 2.4.1 to NCS 2.6.1
My project is based on the coap_server example. When I ported it from NCS 2.4.1 to NCS 2.6.1, the network key and PSKC changed. All other Thread credentials stayed the same (channel, channel mask, panid, extended panid, mesh local prefix, network name, security policy).
The project supports DFU, so when upgrading from a 2.4.1 based version to a 2.6.1 based version, the network key changed and the device cannot communicate with other devices on the original network.
Both versions use identical pm_static.yml files, so the storage settings partition has not moved.
Is this a bug? Is there a workaround?
