APPLIES TO: 2013 2016 2019 Subscription Edition SharePoint in Microsoft 365

You can add a content database to a SharePoint Server farm by using the SharePoint Central Administration website or Microsoft PowerShell. The tool that you use depends on the kind of environment that you have deployed, your schedule requirements, and service level agreements that you have made with your organization.

Before you begin

You can add a new content database or attach an existing content database from a backup file.

Before you begin this operation, review the following information about prerequisites:

• The user account that is performing this operation must be a member of the Farm Administrators SharePoint group.

• If you use Windows authentication to connect to SQL Server, the user account must be a member of the dbcreator fixed server role on the SQL Server instance where the database is to be created.

If you are using SQL authentication to connect to SQL Server, the SQL authentication account that you specify when you create the content database must have dbcreator permission on the SQL Server instance where the database will be created.
