# Migrating keys between cards
If you had keys assigned to an old card, you'll need to delete them and re-assign to a new card. To do that:
1. Find your keygrips on the new card:
```
$ gpg2 --card-status --with-keygrip | grep keygrip
```
2. Delete (or move away) the corresponding files in `~/.gnupg/private-keys-v1.d`
3. Unplug your smart card.
4. Restart `gpg-agent`
5. Plug your card back in and run `gpg2 --card-status`
That should re-assign your keys to the new card.
