SQL Server Upgrade from 2012 Express to SQL Server 2016 Enterprise

Hi all,

We have run production DB on SQL 2012 Express DB (Navision 2016) and want to migrate to 2016 full version . Is there any  traps with that? I plan turn of NAv servers (there are 5 NAS serivice runing ) then use MIcrosoft Data Migration Assistant v3.1 to migrate db's users and other staff to 2016. I suppose when I run Nav servers again everything will start without any Issues . I'm right ? :) 

Thanks
