getMigrationData
Returns all legacy authenticator data as a LegacyExportedData object.
This method is called after isMigrationRequired returns true. The returned object is fed directly into the migration pipeline where OATH and Push mechanisms are extracted and stored in the new credential storage.
Use LegacyDataConverter.convertToLegacyExportedData if your backend implements org.forgerock.android.auth.StorageClient, or construct LegacyExportedData manually for fully custom backends.
Return
LegacyExportedData containing all mechanisms and their associated account data.
Parameters
context
The Android application context.
Throws
if the data cannot be read or deserialised.
