Version and Architecture Upgrade
Last updated: 2025-05-30 10:11:39
Can I change a TencentDB for SQL Server instance from two-node architecture (formerly High Availability/Cluster Edition) to single-node architecture (formerly Basic Edition)?
No. To adjust the architecture, purchase a new single-node (formerly Basic Edition) instance and migrate the data as instructed in Cold Backup Migration.
Can I upgrade TencentDB for SQL Server?
The single-node (formerly Basic Edition), dual-node (formerly HA Edition/Cluster Edition), and multi-node architecture of TencentDB for SQL Server all support version upgrade. See Adjusting the Instance Version.
Can I downgrade the TencentDB for SQL Server version ?
TencentDB for SQL Server doesn't support the version downgrade; for example, you cannot downgrade a Basic Edition instance from v2019 to v2017.
