Enterprise Distributed Application Service (EDAS) supports two types of subscription changes: adjusting instance specifications (the maximum number of application instances) and switching editions (the feature tier). Use upgrade or downgrade operations to match your EDAS subscription to your current workload.
When to upgrade vs. downgrade
| Goal | Action | Example |
|---|---|---|
| Support more application instances | Upgrade specifications | Increase from 200 to 300 instances |
| Access features in a higher tier | Upgrade edition | Standard to Professional or Platinum |
| Reduce unused capacity | Downgrade specifications | Decrease from 300 to 200 instances |
| Lower costs when advanced features are not needed | Downgrade edition | Platinum to Professional or Standard |
