API Gateway: License checking failed when invoking the method

Products

• CA API Gateway

Issue/Introduction

Did an expedited upgrade Gateway 11.0 to Gateway 11.1 via the manual upgrade procedure ->After the DB upgrade, I have been able to start SSG.

But. when I tried to log in with the admin user to Policy Manager to install the new Gateway 11.1 license. I got the below error in the SSG  log and I can not add my new gateway license in the Manage Gateway Licenses task. 

WARNING 458 com.l7tech.server.admin.AdminRemotingProvider: License checking failed when invoking the method, org.springframework.remoting.support.RemoteInvocation#findAllSecurityZones

Environment

Release : 10.x, 11.x

Component : API GATEWAY

Resolution

As this is a new install and you have a valid gateway 11.1 license you can install the gateway 11.1 license on your gateway 11.0 (or higher) environment and migrate it over.

Install new gateway 11.x license on your old 11.x (like 11.0) gateway The gateway supports multiple licenses and the gateway 11.1 license may be used in gateway 11.0 or higher with no issue (although 11.0 will not work in gateway 11.1). 

Then create a new database dump and migrate it over as you did before.  The new gateway should see the gateway 11.1 license installed and you should be able to manage your licenses now.
