Bulk actions

Example use case: Rotate credentials

You use access keys, secrets, and key files to authenticate with your cloud resources. During your data migration project, you need to rotate these credentials.

You migrate data to a single target but you have 30 migrations in progress for that target.

To rotate the credentials for the target, you have to stop all the associated migrations, change the key, and start all the associated migrations again.

To quickly and simply stop and restart all the migrations, you go to the Bulk Actions page in the UI.

Example use case: Filter by source and target, and search by migration name

You have multiple targets and each target has multiple migrations. You need to rotate the credentials for only one of the targets.

Instead of stopping and restarting all the migrations for all your targets, you only want to stop the migrations associated with the target whose key you need to rotate.

To quickly and simply stop and restart only the associated migrations, you go to the Bulk Actions page in the UI and search by migration name.

Migration names are often similar to the path names, so finding all the migrations for a single target or agent with a search term can be tricky.

Use the available source and target filters to further refine your search results. The source filter is particularly useful if you have multiple S3 sources, for example.

Bulk action	Description

Migrations must be in a Stopped or Failed state to appear in the list of migrations available to reset. Under Update Migration Configuration, select Reset Path Mappings to clear the migration's path mapping configuration and automatically use your most recent path mapping configuration. Clear it to continue using the same path mapping configuration from before the reset. Under Skip or Overwrite Settings, select Overwrite if you want the migration to remigrate files that had already been migrated before the reset, regardless of whether the file sizes are the same on the source and target filesystems. Select Skip If Size Match to skip migrating any files that already exist on the target and have the same file size as on the source.
Reset with Target Match	For non ADLS Gen2 live sources. Enable Target Match on reset. Learn more.
