Upgrades

The Unified Engineering environment follows a defined upgrade cadence where Infrastructure and software are updated to new technologies and versions. This cadence also applies to components in the Global Services Add-On.

AVEVA CDO liaise with customers and organize upgrade activities.

Given the hybrid nature of the Global Services Add-On, AVEVA CDO will endeavor to provide as much notice as possible to customers of the newer versions of software, so customers can prepare their on-prem upgrade plans accordingly.

Authentication of the VPN tunnel end-points is dependent on pre-shared keys. These keys will be rotated on each upgrade as a security and control measure. AVEVA CDO will generate the new keys, apply them to the VPN tunnels before upgrading (to prevent global traffic during the upgrade) and after receiving confirmation of on-prem software upgrade complete will pass the keys (securely) to the Customer I.T. who will apply them to their Customer Gateway Device.

Note that software version alignment between Unified Engineering and On-prem is a mandatory pre-requisite to Global Services Add-On availability.
