Migrate steps from v2.5.x to v21.1.x

IMPORTANT ! In order to perform this migration, Orchestrate has to be running on the latest minor version of v2.5.x and been migrated to latest v21.1.x

HashiCorp keys

In order to migrate your keys from kv-v2 engine to orchestrate engine you need to follow the next steps:

1. Instantiate HashiCorp with both engines enabled: kv-v2 and orchestrate
2. Initialize the following environment variables:
   • VAULT_ADDR: HashiCorp host URL
   • VAULT_TOKEN_FILE: Disk path to token file valid for orchestrate engine
   • VAULT_MOUNT_POINT: Mounting point of orchestrate engine
   • VAULT_V2_SECRET_PATH: Path where keys are stored in kv-v2 engine
   • VAULT_V2_MOUNT_POINT: Mounting point of kv-v2 engine
   • VAULT_V2_TOKEN_FILE: Disk path to token file valid for kv-v2 engine
3. Execute command:

   $> orchestrate key-manager migrate import-secrets
   

Orchestrate Service Data

In previous versions of orchestrate each of the API service data was stored in a independent postgres DB. Therefore to update to v21.1.x you need to import each of service’s data by following the next steps for each of the service DBs you intend to migrate:

1. Initialize the following:
   • DB_MIGRATION_SERVICE: Source DB service name. Values are: “chain-registry”, “transaction-scheduler” and “contract-registry”
   • DB_MIGRATION_ADDRESS: Source DB URL
   • DB_MIGRATION_DATABASE: Source DB name
   • DB_MIGRATION_USERNAME: Source DB username
   • DB_MIGRATION_PASSWORD: Source DB password
