If you purchased from a channel partner, please visit that channel partner to acquire the upgrade.
If you purchased directly from Ensim, visit Ensim’s online storefront at https://buy.ensim.com to upgrade existing 3.0 or 3.1 licenses to the new Ensim WEBppliance Pro.
The upgrade is an in-box upgrade to an existing Ensim WEBppliance for Linux server. Customers should read the upgrade guide completely and thoroughly prior to beginning the upgrade. The upgrade guide will call out known (supported and unsupported) customizations and how the upgrade is impacted as a result. Customers will want to schedule a maintenance window and alert their customers to the upgrade.
For standalone customers, WEBppliance Pro will be an in-box upgrade for 3.0 and 3.1. Those customers on 2.4 will still need to migrate to 3.1, then upgrade to Pro.
