Effect of version change on program

  1. Studio version 2019.10.1 to 2019.10.4. Can the original 10.1 program run normally without modification under 10.4?
    Studio 2019.10.1–>Studio 2019.10.4

2.Low version programs run under high version, or vice versa
What’s the impact?
What changes should be made to the program?

look forward to your help

Yes it will work. Just use the same Packages you used in earlier version.

It depends on the package version you used in your processes. Some of the activities may not be available in new version packages.

Check new version release notes before upgrading anything. Based on that you take decision whether to upgrade or not.
