Upgrade Redis Cache from 2.8.9 to Latest

I have a very old Redis Cache instance that needs to be upgraded from 2.8.9 to the latest version 7.2. I don’t have Redis Cache expertise in house, so I’m wondering if there are any breaking changes or major upgrade issues that I need to be aware of in this upgrade path.

  • Can I go directly from 2.8.9 to 7.2 or do I need to install intermediate versions on the way?
  • Any breaking changes between the current and latest version?
  • Any other issues I should be aware of?

Thank you for any assistance!
