It’s recommended for customers to export their current configurations on their own and apply to a new running instance. The good news is that we have a simple and robust solution for upgrading products by running
apt package managers. However, this is for Varnish Custom Statistics and Varnish Enterprise customers only.
We encourage VCS and VE customers to register for support and software updates here. Once registered, you’ll receive an email with instructions on how to setup a software repository.
