Two options I can think of:

Good) Keep your data separate from the UI.  This way you can update the UI
independently of the data.

Not So Good) If you really want to keep the UI and data in the same stack,
include an "export data" option or similar in the stack.  When a user wants
to upgrade they hit "export" and then import the exported data into the
upgrade stack.
