Hello,

Hi, 
 Based on the error you are getting it seems like the issue might be related to this commit . Are you using a custom board or the nRF5340 DK? If you are using a custom board, make sure to add zephyr,bt-hci-rpmsg-ipc = &ipc0; to chosen as is done in the dts files in the commit. Did you remove the build folder completely before building after migrating? Devicetree changes are often not applied even if you do a pristine build, so you will have to delete the build folder completely to make sure the changes get applied. 
 Best regards, 
 Marte
