Can we use SQL Express 2019 running alongside your existing full version SQL 2014 on the same server?

We need SQL2014 for Dynamics NAV and would like using SQL Express for DDM(low cost multi-CAD PDM/PLM solution)so I can work from home and not have to remote my work comupter from home?

    You can install up to 50 named instances of SQL Server on one machine and all can have different versions and different editions, that's fully supported, see

    SQL 2019 express requires at least Windows Server 2016.

    So if your current SQL 2014 instance already runs on Windows Server 2016 both instances should coexist.
    It realy is painfull to search for old support information about deprecated products... but here it is. SQL 2014 should work on Windows Server 2016. Search for 'SQL Server Express' in 'Breadth Editions Operating System requirements' section.

    Some additional guidelines regarding coexistance.

    Hope information helps and no heavy lifting (upgrades and migrations :-) will be required.
