NOTE:

You can use migration.properties to default some of the configuration parameters used for the 4.5 upgrade migration tool: migrateSnapshotsTool.sh migration.properties.

  1. Follow the prompts to determine whether to run for all or specific objects.

What to Expect After Running the Upgrade Migration Tool

When the upgrade migration tool completes running, it prints a result summary for each tenant you specified. If any failures occurred they will be listed with the results.

You must view the Sign file (named migrationTool.<timestamp>. Sign in the same directory as the Incorta Node) to see the results for individual tables.

The upgrade migration tool creates backup files of Direct Data Mapping files (snapshots) for each schema:

Original Direct Data Mapping (Snapshot) File Location Backup Direct Data Mapping (Snapshot) File Location
snapshots/<schema_name>.*.zxt snapshots/backup.<timestamp>/<schema_name>.all.zxt.zip
snapshots/<schema_name>.*.zxi snapshots/backup.<timestamp>/<schema_name>.all.zxi.zip
snapshots/<schema_name>.*.zxc snapshots/backup.<timestamp>/<schema_name>.all.zxc.zip
