As we are moving servers off of Server 2008 R2, we would like to consolidate our MS SQL servers to 1 SQL server. Currently we have 4 SQL servers running on their respective hosts, which also host their respective applications.
In order to move the SQL DB's to a single SQL server, is it best practice to have a separate instance for each DB? Is there best practice documentation for this type of process? The new single SQL server will only host DB's and then the applications will run on dedicated application servers.
Sorry if I am not asking this correctly, but I am not a SQL admin by any means.
Thank you for any insights on this.
