There is no such migration guide. I can only recommend to take the nRF5 SDK example that is closest to your final application, and start from there. You will be able to re-use much of what you have learned from the nRF51 SDKv9 in terms of architecture, but there are changes in all modules and api since then.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
