In API Connect you can have multiple gateway services. I have written about how to add one before but not how to decommission on that is no longer needed.

APIConnect

Step 1 - Remove the APIs from the Gateway Service

This can be done using the script https://chrisphillips-cminion.github.io/apiconnect/2022/07/16/APIC-Gateway-Service-replace.html

Step 2 - Remove the Gateway Service from the Catalogs or Spaces

• Log into the API manager
• Go to each Catalog or Space
• Go to Settings then Gateway services
• Click Edit
• Untick the Gateway Service to be decommissioned.
• Press Save

Step 3 - Remove the Gateway Service from the cloud manager consoles

• Log into the Cloud manager
• Go to topology
• Delete the Gateway Service to be decommissioned.

DataPower

DataPower can be configured in a few different ways and this article is going to cover a high level approach. These steps must be done after the APIConnect steps above.

Containers

Remove the GatewayCluster object for the decommissioned Gateway Service from Kubernetes

Other Form Factors

Remove the domains from each DataPower for the decommissioned Gateway Service
