Arun Sirpal has a series on using the new Data Migration Assistant. Part 1:
It “enables you to upgrade to a modern data platform by detecting compatibility issues that can impact database functionality on your new version of SQL Server. It recommends performance and reliability improvements for your target environment. It allows you to not only move your schema and data, but also uncontained objects from your source server to your target server”. It can be found at this link:https://www.microsoft.com/en-us/download/details.aspx?id=53595.
Part 2 is all about performing a migration:
By the way the backup file created via the tool is temporary, after a migration it is deleted. Also the compatibility level DOES NOT change, you need to do this yourself.
I haven’t used this tool yet, but it does look like an upgrade to the old Upgrade Advisor.
