Honestly, they’re not that dated. I did upgrade them a few years ago, considering it’s such a pain to do a database upgrade with risk and there are no features that I need. I’ve decided to keep them where they are. If I have a need for an improved version of something, I will upgrade it. Case in point, Elasticsearch is on the latest because I needed something for dense vector search, so that got upgraded. When Mongo, Postgres, or Redis have something similar, I’ll upgrade them in time.
