We have a production SharePoint 2010 running in our environment (1xWeb, 1xApp and SQL cluster). We may want to add another SharePoint 2013 farm (segregated from our current 2010 deployment) part of the same domain but we're not sure.
Has anyone done this? Are there best practices to follow? Is there a prebuilt testing VHD already built that includes AD, SQL, SharePoint 2013?
