Bug Report

What did you do?
A clear and concise description of the steps you took (or insert a code snippet).

OLM extends Kubernetes to provide a declarative way to install, manage, and upgrade operators and their dependencies in a cluster.

There is not mentioned that OLM downgrade support. I just wonder to know if we support downgrade or not.

What did you expect to see?
A clear and concise description of what you expected to happen (or insert a code snippet).

When I use helm to upgrade, I can use helm downgrade to rollback the previous version. But from the document and my testing, I did not find the way how to download by OLM.

@camilamacedo86 @dinhxuanvu I saw there is a document mentioned that the downgrade - https://github.com/operator-framework/operator-lifecycle-manager/blob/master/doc/design/dependency-resolution.md#dependency-resolution

Could you please elaborate more details? Thanks.

FYI @gyliu513

The downgrade that has been mentioned in that document is referring more to an attempted upgrade that is reverting, rather than explicitly supporting an arbitrary downgrade. Philosophically, OLM is designed to always upgrade to the next version. If an emergency fix is needed, that fix should be made in a new CSV to be made available to OLM.

@jpeeler Thanks for you reply. If we want to rollback the previous version(I do not like this new version), there is no way by using olm. You have to reinstall.
