 #### State Migration
 State migration allows the transfer of critical program data from an old program to a new one, enabling smooth upgrades while preserving important state variables. In this example, the migration involves exporting specific fields (`value`, `limit`, and `contributions`) and importing them into a new instance of the program.
 1. Exporting State
-The `export_migration_state` function serializes only the necessary fields from the program's state and encodes them for transfer.
