Can SQL Server 2016 Express be installed (safely) over SQL Server 2014? I don't want to have to uninstall any of the SQL Server 2014 if I can avoid it.
What I have tried:
Yesterday I tried to uninstall all the SQL Server 2014 before installing SQL Server 2016 Express. Caused a problem I couldn't figure out, and I wound up having to restore the whole disk drive.
