--- title: Step 2. User Data Migration sidebar: order: 3 --- Once your user accounts have been migrated over to SuperTokens, additional information like metadata, roles and permissions can be associated with the user. ## User Metadata Migration SuperTokens allows you to store arbitrary data that is JSON serializable against a userId. In this example we want to store the following metadata against our user: ```json { "someKey": "someValue" } ``` ```bash curl --location --request PUT '/recipe/user/metadata' \ --header 'api-key: ' \ --header 'Content-Type: application/json; charset=utf-8' \ --data-raw '{ "userId": "5acb2dbc-04f0-4c80-822a-7f06cd658f6f", "metadataUpdate": { "someKey": "someValue" } }' ``` ## User Roles Migration SuperTokens allows you to assign roles and permissions to a userId. In this example we will be assigning the `admin` role to a user: ```bash curl --location --request PUT '/recipe/user/role' \ --header 'api-key: ' \ --header 'Content-Type: application/json; charset=utf-8' \ --data-raw '{ "role": "admin", "userId": "5acb2dbc-04f0-4c80-822a-7f06cd658f6f" }' ``` :::info[Important] Roles and permissions must be created before they can be assigned to a user. You can follow this [guide](/additional-verification/user-roles/initial-setup) on creating roles and permissions in SuperTokens. ::: --- ## See also
