The systems and methods provide for planned upgrades and downgrades for network devices without impacting existing network sessions, by utilizing two network devices simultaneously, and creating a redirect network session for a predetermined period of time. In so doing, all network traffic may be gradually transferred to the second network device, until the sessions processed by the first network device time out. The first network device can then be taken offline for upgrade or downgrade, without any disruption to the network service or loss of network traffic."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enabling planned upgrade/downgrade of network devices without impacting network sessions","description":"Exemplary embodiments for enabling planned network changes such as an upgrade or downgrade of a network device are disclosed.
