I have a SQL Server 2014 database (on a portable hard drive) which I had to attach to a SQL Server 2016 machine using the normal attach method.
However, since attaching it to that computer, it no longer works on the SQL Server 2014 computer even though I didn't change the compatibility level or anything else for that matter.
I'm now stuck because SQL Server 2016 will not work on Windows 7 machines which is what all the other computers run on. I just happened to attach it on a laptop running Windows 10 and SQL 2016 thinking it wouldn't be a problem.
Is there any way to reverse this situation? I'm not able to get any good information from the error screen in management studio.
