Separate Vcenter and Database Server

Hello,

we are running a Vcenter Server 5.5 with the default MS-SQL Server Express database.

We have now started a project to consolidate all our other SQL-Express databases on a MS-SQL Server Standard Edition, so that we have better monitoring and backup options.

Is this a recommended strategy for the Vcenter-Database? What happend with the Vcenter for example, if I need to recover the database to an older version (for example a few hours or one day ago)?

Are there any Best Practice Guides available?

Thanks.
