Experience with XAML Builds in Azure DevOps 2020 on prem Upgrade to latest Azure DevOps Version
Hello everyone,
I am planning to upgrade our current DevOps environment to the latest Version (Upgrade path is given by Microsoft Docs).
Unfortunately, we don't have a second environment to test the upgrade so maybe someone of you has some experience.
What we do have is that the Machine where our Azure DevOps instance is running is fully virtualized. We can do snapshots and restore. (HyperV)
Our instance unfortunately still uses XAML Builds for an legacy application that is still used by a lot of customers and is Business critical. These are sre not easy to migrate and are highly intertwined with business logic and some other dependecies. In Short: A Nightmare. We also use Classic Pipelines and Releases.
I know that XAML Builds are deprecated, but i inherited the Environment and the old engineer that build the whole Thing is not in the company anymore. So it is still kind of a "blackbox".
We could just snapshot the Environment before the upgrade and rollback. Never done it, but i think it should work if shit would hit the fan.
Does anyone have experience with Upgrading to a newer Version and XAML Builds?
What would be the best approach here?
