Planning to move to new hardware for your SQL Server? Techniques like log shipping and database mirroring can be incredibly useful to make the change fast and painless– but you’ve got to pick the right techniques for your environment ahead of time, and know how to do a few things that aren’t in the GUI.
Here are some of my favorite whitepapers and resources to get you going.
