Upgrading

Upgrading Pritunl IPsec links

When upgrading links it is recommended to deploy a new link host instead of upgrading an existing host. This will prevent unexpected downtime and allow quickly rolling back the upgrade if an issue occurs. To deploy an upgraded host first create a new host in the link location then set the priority of the host higher then the priority of the existing hosts. This will force the link to run on the new host when it becomes available. Then deploy the new host using the instructions in the IPsec Peering section. Once the new host is active the old host can be removed. If an issue occurs increase the priority of the old host to a higher priority then the new host to roll back the upgrade.
