Database Server Software Requirements
SQL Server 2012, SQL Server 2014, SQL Server 2016, or SQL Server 2017 with Client Tools (SQL Management Studio, SQL Server Agent, latest service packs). Ensure the SQL Servers are 64-bit (OS and SQL Server).
Workspace ONE UEM does not support Express, Workgroup, or Web editions of SQL Server. These editions do not support all the features used in the Workspace ONE UEM application. Currently only Standard and Enterprise Editions are supported.
