# Moving to a New Identity Provider

## Retaining subject IDs in Naviga ID

Moving to a new identity provider will, most of the time, involve a new subject ID for the user, resulting in a new subject ID in Naviga ID as well. To retain the users Naviga ID subject ID, the `http://infomaker.io/originalSubject` claim can be added to the organization token. This claim should consist of the subject ID the user had in the previous identity provider.

```
{
    "sub": "subject-id-from-current-idp"
    "http://infomaker.io/originalSubject": "subject-id-from-previous-idp"
    ...
}
```

When encountering the `http://infomaker.io/originalSubject` claim, Naviga ID will replace the previous subject ID stored internally with the subject ID found in the `sub` claim.
