What hurdles would be expected upgrading from v0.32.1 to the current release of v1.6.0

I was reviewing the release notes for v1.0.0 https://github.com/tektoncd/pipeline/releases/tag/v1.0.0 and didn't really spot anything mentioned about breaking changes and incompatibilities.

For users that are still running tekton v0.32.1 what pain points would be expected moving to a 1.x version of tekton pipeline if any?

v0.32.1 was released in January 2022, so there have been a lot of changes made since - new features, deprecations, removal of old features, etc. It's not just v1.0 that introduced breaking changes.

Any breaking changes would have been first introduced in a backwards compatible manner, typically with an opt-in feature flag or working alongside the existing functionality, before being enabled by default for some period, and eventually the flag being removed a few releases later.

You can see details of some of the deprecated / removed features in https://github.com/tektoncd/pipeline/blob/main/docs/deprecations.md

For a complete list of breaking changes you should carefully review the release notes of each minor release between v0.32 and v1.6. Any breaking changes or required actions would be identified clearly in the release notes.

Just taking a few releases as examples:

• See the deprecation notices and upgrade notices in v0.33
  
• Backwards incompatible changes in v0.34
  
• etc.

@jxramos If this answered your question I'd appreciate if you could mark it as answered, to help other users who may be searching the discussions with similar questions in future.

You will need to move it to the Q&A category to enable this, which you can do by clicking the gear icon beside 'Category' at the top of the right sidebar and selecting 'Q&A'. Once it's moved, you should see a 'Mark as answer' button on the comment above.

That deprecations page may be the one for me to review. That language of “backwards incompatible changes” like used in the screenshot above does not show up in the deprecations page but I do see a group of “removed features” to share with the team. Thanks so much for putting this together.
