Hey, I'm one of the maintainers of Valkey. I just wanted to drop by to add some more context. Feel free to @me with questions if you have any.

Argo CD is several versions behind on Redis as it is and security updates are going to be offered for supported BSD versions of Redis until Redis Community Edition 9.0 which should arrive sometime in 2026.

I want to highlight that most of the top contributors are no longer working on Redis Community Edition, and moved to Valkey. Yes there will be support, but we already have fixes in our 7.2.5 that weren't present in their latest 7.2 release. Also it seems you are on 7.0, which will have its support dropped sooner (Unless they changed their support policy, it'll be in 2025).

We have time to make an informed decision.

I think this is the right framing, don't rush the decision. My guidance so far has been to wait until you would normally do an upgrade and then treat the move to Valkey as a minor version bump. We are fully compatible, so it's easy to test on, but take your time.
