Validating Upgrades and Backing Up the Cluster

Validation for upgrades

Before we jump into different upgrade options, I must make an important statement. Do not trust anyone or anything blindly. We (the community behind Jenkins X) are doing our best to make it stable and backward compatible. Upgrading should work, but that does not mean that it will always work. No matter how much attention we put into making the project stable, there is almost an infinite number of combinations, and you should make an extra effort to test upgrades before applying them to production, just as you’re hopefully validating your applications.
