# Migrations This document describes breaking changes and migrations between Constellation releases. Use [`constellation config migrate`](./cli.md#constellation-config-migrate) to automatically update an old config file to a new format. ## Migrating from Azure's service principal authentication to managed identity authentication - The `provider.azure.appClientID` and `provider.azure.appClientSecret` fields are no longer required and should be removed. - To keep using an existing UAMI add the `Owner` permission with the scope of your `resourceGroup`. - Otherwise, simply [create new Constellation IAM credentials](../workflows/config.md#creating-iam-credentials) and use the created UAMI. - To migrate the authentication for an existing Constellation on Azure to an UAMI with the necessary permissions: 1. Remove the `aadClientId` and `aadClientSecret` from the azureconfig secret. 2. Set `useManagedIdentityExtension` to `true` and use the `userAssignedIdentity` from the Constellation config for the value of `userAssignedIdentityID`. 3. Restart the CSI driver, cloud controller manager, cluster autoscaler, and Constellation operator pods. ## Migrating from CLI versions before 2.8 - The `measurements` field for each cloud service provider was replaced with a global `attestation` field. - The `confidentialVM`, `idKeyDigest`, and `enforceIdKeyDigest` fields for the Azure cloud service provider were removed in favor of using the global `attestation` field. - The optional global field `attestationVariant` was replaced by the now required `attestation` field. ## Migrating from CLI versions before 2.3 - The `sshUsers` field was deprecated in v2.2 and has been removed from the configuration in v2.3. As an alternative for SSH, check the workflow section [Connect to nodes](../workflows/troubleshooting.md#node-shell-access). - The `image` field for each cloud service provider has been replaced with a global `image` field. Use the following mapping to migrate your configuration:

- The `enforcedMeasurements` field has been removed and merged with the `measurements` field. - To migrate your config containing a new image (`v2.3` or greater), remove the old `measurements` and `enforcedMeasurements` entries from your config and run `constellation fetch-measurements` - To migrate your config containing an image older than `v2.3`, remove the `enforcedMeasurements` entry and replace the entries in `measurements` as shown in the example below: ```diff measurements: - 0: DzXCFGCNk8em5ornNZtKi+Wg6Z7qkQfs5CfE3qTkOc8= + 0: + expected: DzXCFGCNk8em5ornNZtKi+Wg6Z7qkQfs5CfE3qTkOc8= + warnOnly: true - 8: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= + 8: + expected: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= + warnOnly: false -enforcedMeasurements: - - 8 ```
