With the release of Microsoft SQL server 2019 on the horizon, we started testing the compatibility of Dynamics GP 2018 and the beta version of Microsoft SQL server 2019 this week. I got chance downloaded and installed SQL server 2019 preview on Windows server 2019 preview with GP2018. What we have found so far is some compatibility issues with database versions. We plan to test with GP2018R2 when it is available and will provide updates along the way. We doubt if GP2018R2 will be compatible either, GP2019 maybe. For now, anyone planning to be an early adopter of SQL server 2019 should wait until Microsoft certified it.
