Migration

VeloDB Cloud provides an efficient, secure, one-stop data migration function. Use it to move full data from Apache Doris or VeloDB Enterprise into a VeloDB Cloud warehouse.

To create a migration task, follow these steps:

1. Log in to the VeloDB Cloud console.
2. In the upper-left corner, select the warehouse that you want to use.
3. In the left navigation pane, click Data Integration.
4. Click Add Migration Job on the initial page. If this page already contains jobs, in the upper-right corner, click Add Data > Migrate to VeloDB Cloud.
5. Select Apache Doris or VeloDB Enterprise, then click Continue.

1. Connect to the source cluster

Fill in the task name and description, then enter the source cluster's connection details: JDBC port, HTTP port, username, and password. Click Next to verify connectivity.

2. Configure temporary object storage

Pick an object-storage provider and fill in the bucket address and authorization information. VeloDB Cloud uses this bucket as a temporary staging area during migration and cleans it up automatically after the task finishes.

3. Select databases and tables

Pick the databases and tables to migrate. You can select them in batches or use custom filters. You can also add row-level data filters for each table.

4. Set migration resources

Choose the cluster that will perform the migration, and set the concurrency:

• Table concurrency: how many tables migrate in parallel.
• Tablet concurrency per table: how many tablets of a single table migrate in parallel.

5. Run the pre-check and start

A pre-check runs automatically. When it passes, start the migration task.

Monitor migration tasks

On Data Integration, select Migration Jobs. The list shows each task's name, data source, status, and creation time.

Click a task to see detailed progress, per-table status, and any errors.
