Full/Simple Migration

• Full – Moves separate options into unified option collection
• Performed at most once per request
• Generally only when version is changed (or forced manually)
• Simple – Remaps internal option items (in options collection)
• Renamed options, legacy (removed) options, etc.
• ? Performed more than once per request?
• A No: Options renamed at file-level, not at runtime
• Can occur even though version has not changed
• Don’t want to change version just for renaming options
• Should be fast
