SharePoint databases are running in a instance SP16 on Microsoft SQL Server 2016 (SP1) on a Windows Server 2012 R2 Datacenter at the moment. SharePoint is installed with 4 machine MinRole WFE-APP-Search-DC.
We want to get rid of the Windows Server 2012 R2 and want to have SQL Server running on a newer Version of Windows Server. Due to this the complete SQL Server instance or all containing databases have to move to a new server being the new SQL Server.
Planning to shutdown SharePoint, backup/restore databases to new SQL Server and run config wizard on SharePoint App Server.
Any experiences with this? Is this enough or do I have to keep something else in mind?
