Choose an LTS Upgrade Path
API7 Gateway long-term support (LTS) upgrade routes define the required source and target versions, production topology, compatibility changes, and rollback procedure. Select the route for the current source release before preparing the deployment.
Available LTS Upgrade Paths
The following self-service routes have pair-specific guides:
| Source LTS | Target LTS | Details |
|---|---|---|
| 3.9 | 3.10 | Upgrade from 3.9 LTS to 3.10 LTS |
| 3.8 | 3.10 | Upgrade from 3.8 LTS to 3.10 LTS |
Both routes target version 3.10.8. The 3.9 route starts from 3.9.21, and the 3.8 route starts from 3.8.23. If the source is on an earlier patch, first upgrade it to the version named in the pair-specific guide.
Open the guide for the source release and confirm that the deployment meets its applicability requirements. Otherwise, contact API7 Support for a topology-specific or staged plan. A staged plan from 3.8 may pass through 3.9 and must satisfy the requirements for both transitions.
The general upgrade strategies explain the underlying deployment mechanics. Follow the pair-specific guide or API7 Support-provided plan for the production procedure.
