Given the introductory clause ("It's pretty much the same as any other
operation on with a MOC"), this is potentially misleading. This applies to the
specific case where you want to move data from one store to another.
For "typical operations with a context", you don't want to move records between
stores. If you're using multiple contexts, the more likely scenario is that you
have a realisation of a given record in one context and you want another
realisation of the same record in another context. For that you do not
*create* new objects in the second context (and you don't *delete* the old
objects in the first context); instead you ask the context for a managed object
using objectWithID: or similar.
