Adding a Name Prefix or Path Prefix to Migrated Objects

Overview

The Specify Prefix parameter enables you to:

• Add a name prefix to objects migrated to the destination bucket.

  For example, if you set Specify Prefix to Yes and specify the prefix Test-Prefix when you create a migration task or task group, source objects oms_a.txt and oms_b.txt will be renamed Test-Prefixoms_a.txt and Test-Prefixoms_b.txt after they are migrated to the destination bucket.

• Add a path prefix to objects migrated to the destination bucket.

  For example, if you set Specify Prefix to Yes and specify the path prefix Test-Prefix/ when you create a migration task or task group, OMS will create a Test-Prefix/ directory in the root directory of the destination bucket, and migrate source objects, such as oms_a.txt and oms_b.txt to it. The paths to oms_a.txt and oms_b.txt will be Destination bucket name/Test-Prefix/oms_a.txt and Destination bucket name/Test-Prefix/oms_b.txt.

Scenarios

This section uses the File/Folder migration method as an example to describe how to configure Specify Prefix during the creation of a migration task or task group.

You can use Specify Prefix to:

• Add a name prefix to migrated files.
• Add a path prefix to migrated files.
• Add a name prefix to migrated folders.
• Add a path prefix to migrated folders.
• Add a path prefix to the whole bucket.

Add a Name Prefix to Migrated Files

1. Log in to the Huawei Cloud console.
2. Click in the upper left corner and select the region where the destination bucket is located from the drop-down list.

3. Click Service List in the upper left corner, and choose Migration > Object Storage Migration Service.
   You can also enter OMS in the search box to quickly find OMS.

6. Set parameters in the Select Source area. For details, see Table 1.

   Table 1 Parameters for configuring a source bucket

   Parameter	Configuration
   Data Source	Select Huawei Cloud.
   Access Key ID	Enter the AK for the Huawei Cloud account to which the source bucket belongs.
   Secret Access Key	Enter the SK for the Huawei Cloud account to which the source bucket belongs.
   Specify Source Bucket	If you disable Specify Source Bucket (which is disabled by default), you need to: Select the bucket where the source data is stored from the Bucket drop-down list. OMS will check whether the source platform can be connected using the information you provided. Once the source platform is connected, all buckets in your account will show up in the Bucket drop-down list, provided your account has the necessary permissions to list buckets. NOTE: If the source account does not have the permissions required to list buckets, you need to enable Specify Source Bucket.
   	If you enable Specify Source Bucket, you need to: Select the region where the source bucket is located from the Region drop-down list. In the Bucket text box, enter the name of the bucket or the directory to be migrated. The directory must have the bucket name included. Click Connect.

7. Set parameters in the Select Destination area and click Next. For details, see Table 2.

   Table 2 Parameters for configuring a destination bucket

   Parameter	Configuration
   Access Key ID	Enter the AK for the Huawei Cloud account to which the destination bucket belongs.
   Secret Access Key	Enter the SK for the Huawei Cloud account to which the destination bucket belongs.
   Bucket	Select a destination OBS bucket for storing the migrated data.

8. On the displayed Set Task Parameters page, set parameters.
