RAM-based Access Control
- Authorize DTS to access Alibaba Cloud resources
- Use a system policy to authorize a RAM user to manage DTS instances

Best Practices
- Switch workloads to the destination database
- Use triggers and functions to implement incremental DDL migration for PostgreSQL databases
- Disable slow query log to improve migration performance
- Change the character set of an ApsaraDB RDS for MySQL instance
- Configure a data synchronization task for a source database that contains a trigger
- Migrate data between databases that have different names
- Disaster tolerance of data subscription SDK
- Set a cache update policy by using the change tracking feature

Troubleshooting
- Common error codes and troubleshooting methods
- What can I do if full data migration stops or slows down?
- How do I troubleshoot the incremental migration latency or synchronization latency of DTS?
- What do I do if a connection failure occurs when I configure a task?
- What can I do if data loss occurs in the destination database due to inconsistent case sensitivity of character sets in the source and destination databases?
- What can I do if data loss occurs in the destination database due to online DDL operations performed in a table merging task?
- Precheck failed
