This tutorial explains how to migrate from Aliyun OSS in the Singapore region to UCloud Global US3 in the Bangkok region. The migration architecture diagram is as follows:

一、Preparations

1.1 Purchase a UHost instance in the Bangkok region

Public IP: 128.1.79.13

Private IP: 10.31.87.189

After purchasing the UHost, click 'Login' or remotely access the host.

1.2 Set up the migration environment

Enter the following commands in order (requires root user privileges):

yum install -y telnet expect rsync

wget https://ufile-release.cn-bj.ufileos.com/US3SYNC/v1.10.5_beta02/US3SYNC.tgz 

tar -zxvf US3SYNC.tgz

cd ./US3SYNC

./console.sh start

Access US3SYNC at the following link: https://128.1.79.13 (UHost Public IP)

1.3 The UCloud US3 endpoints for different regions are as follows:

二、Aliyun Singapore OSS to UCloud Bangkok US3 Migration

2.1 Set the Aliyun OSS migration endpoint

We have already created an OSS bucket named ‘aliyun-singapore-src’ on Aliyun. Then you follow the steps below on the console of Aliyun:

The two images above contain four values that need to be recorded:

1. Bucket name: aliyun-singapore-src 

2. Endpoint: oss-ap-southeast-1.aliyuncs.com 

3. AccessKey ID 

4. AccessKey Secret

Return to the US3SYNC, then enter the four recorded values. Click ‘OK’.

2.2 Set the Migrating Nodes

Enter the private IP of the Bangkok UHost, input the UHost username and password, and specify the Working Directory. Click ‘OK’.

2.3 Set the UCloud Global US3 endpoint

In the UCloud Global console, purchase a US3 in the Bangkok region and set the name as ‘bangkok-mig-destination’.

Create a new Token and select the bucket in the Bangkok region.

The following four values need to be recorded:

1、 bucket name: bangkok-mig-destination

2、 Public key: TOKEN_81ced282-ad49-47e5-827c-2f7c920f0325

3、 Private key: TOKEN_81ced282-ad49-47e5-827c-2f7c920f0325

4、 Domain name: internal-th-bkk.ufileos.com (Since both the migration UHost and US3 are located in Bangkok, we can use the private domain name. For details, refer to section 1.3)

Fill in the recorded values as shown in the image, and click "OK".

2.4 Implement the US3SYNC migration task

Create task and fill in the required information as instructed.

The image above indicates that the migration was successful, with a total of one file migrated.

Check the UCloud Global console to verify that the file has been successfully migrated to US3.
