Please help us help you and fill where relevant:
Your LimeSurvey version:  Version 5.4.11+221114

We are thinking about migrating our existing LimeSurvey, which is using MySQL, to a version of Microsoft SQL Server.

Has anyone done this?  If so, what steps did you follow and what version of MS SQL Server?

Thanks
