It’s better to execute pilot migration. Start with non-critical, small-scale, and low-dependency systems to verify the new data center environment (network/compute/storage). Summarize pilot experiences and adjust subsequent migration plans iteratively.

Here are some tips when you perform migration:

• Start with simple systems, such as single-server systems.

• Migrate general business systems before core systems.

• Migrate systems with smaller data volumes first, then larger ones.

• Prioritize migrating applications before databases. For databases, it’s better to use the database's native tools and cluster for migration.

• Avoid changing the existing network architecture of business systems as much as possible.

• Make full use of holidays and nighttime for migration, with thorough validation, to minimize the impact on daily business operations.
