V2Migration updates the repo so that nodeID is no longer part of the execution and job store paths. It does the following: - Generates and persists the nodeID in the config if it is missing, which is the case for v2 repos - Adds the execution and job store paths to the config if they are missing, which is the case for v3 repos - Renames the execution and job store directories to the new name if they exist

var V3Migration = V3MigrationWithConfig(system.DefaultGlobalConfig)

V3Migration updates the repo, replacing repo.version and update.json with system_metadata.yaml. It does the following: - Creates system_metadata.yaml with repo version 4. - Sets the last update check time in system_metadata.yaml to Unix time zero. - If an installationID is present in the config, its value is persisted to system_metadata.yaml. - Removes update.json if the file is present. - Removes repo.version. - Creates a new directory .bacalhau/orchestrator. - Moves contents of .bacalhau/orchestrator_store to .bacalhau/orchestrator and renames jobs.db to state_boltdb.db. - Removes .bacalhau/orchestrator_store. - Creates a new directory .bacalhau/compute. - Moves executions.db from .bacalhau/compute_store to .bacalhau/compute/state_boltdb.db. - Creates a new directory .bacalhau/compute/executions. - Moves contents of .bacalhau/execution_store to .bacalhau/compute/executions. - Removes ./bacalhau/execution_store. - If a user has configured a custom user key path, the configured value is copied to .bacalhau/user_id.pem. - If a user has configured a custom auth tokens path, the configured value is copied to .bacalhau/tokens.json.
