@ldowen @jmikeowen If this is ready, can we run a test install with a tag e.g. "risky-test" to ensure this works as intended on production installs.

[jmikeowen]

@mdavis36 @ldowen , I agree it would be great to test with a tag as Mike suggests. Can we do that still in the branch?

[mdavis36]

@ldowen @jmikeowen It will trigger the pipeline for a tag on any branch. We just need to go in and manually trigger the production jobs for the installation once the pipeline has started and completed the normal set of build and test jobs.

@ldowen @jmikeowen Looks good to go
