Automated configuration transfer for containerized applications

A method, executed by a set of computing devices, of configuring a new containerized application operating in a first container on a hypervisor of the set of computing devices to replace an old containerized application operating in a second container on the hypervisor, wherein the new containerized application is a newer version of the old containerized application, the method comprising:

• initiating installation of the first container and the new containerized application on the hypervisor;
• in response to receiving, from the new containerized application, a request for a license identifier (ID) of a licensing service, sending the license ID from the old containerized application to the new containerized application, the license ID being associated with the old containerized application;
• sending an instruction to the old containerized application directing the old containerized application to dissociate from the license ID;
• sending a dissociation request from the old containerized application to the licensing service to cause the licensing service to dissociate the old containerized application from the license ID;
• in response to dissociating the old containerized application from the license ID, sending a confirmation from the old containerized application to the new containerized application to confirm that the old containerized application has dissociated from the license ID;
• and
• in response to the confirmation, associating the new containerized application with the license ID to license the new containerized application with the licensing service.

A system for configuring a new containerized application operating in a first container to replace an old containerized application operating in a second container of a hypervisor of a set of computing devices, wherein the new containerized application is a newer version of the old containerized application, the system comprising:

• the set of computing devices configured to:
• initiate installation of the first container and the new containerized application on the hypervisor,
• in response to receiving, from the new containerized application, a request for a license identifier (ID) of a licensing service, send the license ID from the old containerized application to the new containerized application, the license ID being associated with the old containerized application,
• send an instruction to the old containerized application directing the old containerized application to dissociate from the license ID,
• send a dissociation request from the old containerized application to the licensing service, and
• in response to dissociating the old containerized application from the license ID, send a confirmation from the old containerized application to the new containerized application to confirm that the old containerized application has dissociated from the license ID;
• and
• a licensing server configured to execute the licensing service, the licensing server connected to the set of computing devices via a network,
• wherein the licensing service is configured to:
• dissociate the old containerized application from the license ID in response to the dissociation request,
• receive an association request from the new containerized application to associate the new containerized application with the license ID, and
• in response to the confirmation and receiving the association request, associate the new containerized application with the license ID to license the new containerized application with the licensing service.
