    Server Migration Center:Manage migration sources and jobs with tags

    Last Updated:Jun 03, 2026

    Use tags to categorize migration sources and jobs for filtering and batch operations.

    Limitations

    Each tag is a key-value pair. Limitations:

    • Tag keys must be unique per resource. Adding a duplicate key overwrites the existing value. For example, adding department:FD to a source with department:MD removes the department:MD tag.

    • Maximum 20 tags per resource. Tags are case-sensitive.

    • Deleting all resources that use a tag also deletes the tag.

    • Removing a tag from its last associated resource deletes the tag.

    • Tag creation constraints:

      • Key (required): up to 64 characters. Cannot start with aliyun or acs:, or contain http:// or https://.

      • Value (optional): up to 128 characters. Cannot start with aliyun or acs:, or contain http:// or https://.

    Add tags to migration sources and migration jobs

    You can tag a migration source after importing it, or tag a migration job during or after creation. The following example uses a server migration source; the procedure is similar for other types.

    1. Go to the Server Migration page in the SMC console.

    2. Find the migration source to tag. In the Tag column, click the Tag icon and then click Edit.

      You can also add tags when creating a migration job. Migrate servers to ECS.

    3. In the Configure Tags dialog box, add or edit tags.

      Enter a new key-value pair or select an existing one.

      Note

      You can add up to 20 tags to each resource.

    4. Click Confirm.

      To view tags, hover over the Tag icon in the Tag column of the migration source or job list.

      Note

      To edit or remove tags, hover over the Tag icon and click Edit. In the Configure Tags dialog box, click the x next to a tag to remove it.

    Filter migration sources by tag

    Filter migration sources by tag to quickly locate resources for batch management. The following example uses a server migration source; the procedure is similar for other types.

    1. Go to the Server Migration page in the SMC console.

    2. On the Migration Sources page, click Filter by tag.

    3. Select a tag key and a tag value to filter the migration sources.

      The page shows migration sources matching the specified tag.

      Note

      • Selecting only a tag key returns all migration sources with that key, regardless of value.

      • To remove a filter condition, click the x next to the tag.
