Upgrade or downgrade a Microservices Engine (MSE) instance to match your current workload. You can adjust the engine specification tier, cluster node count, and network configuration.
Before you begin
A specification change takes about 10 minutes. During this period, you cannot perform other operations on the instance in the MSE console.
Clients temporarily lose connections during the change. Schedule changes during off-peak hours to minimize disruption.
Availability during the change
| Instance type | Behavior | Service impact |
|---|---|---|
| 3+ nodes | Rolling deployment. Nodes update one at a time with automatic data synchronization. | None. Your business is not interrupted during the process. |
| 1-2 nodes | No high availability. | Services may be interrupted during the change. |
