Overview

Migrating from Alibaba Cloud OSS to Azure Blob Storage is ideal for organizations leveraging Microsoft's enterprise ecosystem or expanding their presence with Azure's hybrid cloud solutions. This guide provides a complete migration walkthrough using Cloney.

Migration Benefits

Azure offers seamless Microsoft 365 integration, strong enterprise features, and extensive hybrid cloud capabilities.

Prerequisites

  • A Cloney account with an active subscription
  • Alibaba Cloud OSS bucket with data to migrate
  • Azure account with a Blob Storage container created
  • Appropriate credentials for both services

Setup Access Credentials

Before proceeding, ensure you have configured least privilege access for both services:

Step 3: Start the Migration

  1. Configure optional settings (prefix filter, access tier, metadata)
  2. Review your migration configuration
  3. Click Start Migration
  4. Monitor progress in the Jobs dashboard
Migration Complete

Once finished, verify your data in the Azure Portal and update your applications.

Best Practices

  • Test with a subset first: Run a pilot migration with a small subset of data to validate your configuration.
  • Choose the right Azure region: Select a region close to your users for optimal performance.
  • Enable soft delete: Consider enabling soft delete for blob protection.
  • Plan access tier transitions: Configure lifecycle management policies if needed.
