   Added a clarifying note that after migration, the original legacy wallet file remains unchanged on disk as a backup. This helps users understand that migration is non-destructive.

   I don’t see why this is needed. There is are already more specific instructions about the backup file in the previous paragraph. The term “backup” already implies that it will not be changed.

   Agree.

   Closing for now, but discussion can continue.
