I am trying to access a project that was done using Unity 5.5. I am complete beginner to Unity so my question is: will I still be able to execute code with Unity 5.6 even though it was worked with Unity 5.5? Will it be necessary to uninstall and reinstall older version to avoid any possible bugs and incompatibility issues?
When you first load a project last saved with an older version of Unity, it will be auto-upgraded. It will then work fine in 5.6, but you can’t then reopen it in an older version.
