Systems and method to enhance session offloading during failover in high availability (ha) environment

A system comprising:

• one or more processing resources;
• and
• a non-transitory computer readable medium coupled to the one or more processing resources and having stored therein instructions being executable by the one or more processing resources cause the one or more processing resources to:
• establish sessions in a first network appliance initially having a primary role for processing network traffic having data packets;
• upon establishing sessions in the first network appliance, perform a synchronizing process to offload relevant session information for the sessions to a second network appliance initially having a secondary role;
• and
• concurrent with the synchronizing process, offload the relevant session information to one or more network processing resources of the second network appliance to ensure that offloaded sessions of the one or more network processing resources are ready to be used on the second network appliance if a Failover process is initiated from the first network appliance to the second network appliance.
