Create a one-time migration
One-time migrations do not track activity in your data during a migration. If you create a one-time migration, your LiveData Migrator instance will not scan your source storage for updates to the data as the migration progresses.
A one-time migration does not write a marker file to the source storage. Once the scan of the source completes (to determine which files and directories are to be migrated), the migration will enter a COMPLETED
data migration state and won't perform any further scans.
- Create a one-time migration with the Azure Portal
- Create a one-time migration with the CLI
- In the Azure Portal, navigate to the LiveData Migrator resource page.
- From the LiveData Migrator menu on the left, click Migrations.
- Click Add.
- Complete the Basic details:
- Target storage: your ADLS Gen2 storage account.
- Path: the directory on your Hadoop edge node to migrate data from.
- Click Next: Migration Settings.
- Complete the Migration settings:
- Target Action Policy: overwrite all the content (Overwrite) or only migrate new content that isn't already there (Skip).
- Automatically Start Migration: start the migration right away, or start it manually later.
- Enable Live Migration: change this option from the default 'Yes' to 'No'.
- Click Review and create.

Your created one-time migration will display the parameter Live Migration: No
in the migration overview.
