Should you upgrade lower or higher environment first and why

Certified Senior Developer

Hi All,

I came across a question where the environment should get upgraded to latest version. Should we start upgrading the higher environments first and go down to lower environment upgrade or vice-versa, and what will be the impact in both cases. Can someone help in knowing this impact?

    There is one issue with upgrades. You cannot deploy from a higher version to a lower. In case you upgrade the lower first, you stop the development process until the higher one is upgraded as well.

    Our clients typically have 3-4 environments. We start in the middle to find any issues, then higher first, lower last to keep the option for hot fixes.

    Hi Stefan,

    Considering we aren't making any new changes to push from a lower environment (Higher Version) to higher environment (Lower Version), what else can be the challenge in updating the lower environment to a higher version before updating the higher environment, any other challenges you can think of?
