Can you describe this process, especially for how it can be accomplished with a single (local) cache?

A migration mechanism is absolutely a must. There are ModeShape users that have used the FCS simply because it suits their needs - primarily because there are no extra dependencies and no additional "system" underneath. There HAS to be a migration path, especially if the old FCS is going to be removed.

Why does Infinispan not have a general-purpose mechanism for converting from one (offline) cache store to another (offline) cache store?
