Redmine

Hi,

I would like to update my redmine 4.0.6 version to 4.1.x version. The most important feature that i would like to use is the gant expand/collapse.
I red the new (4.1.x) version knew this function.

Could you send me a step by step descripiton to the update method?

The redmine is on an Ubuntu 20.04 LTS with ruby 2.7.0 version.

it can also be a solution, install a new operating system with new redmine (4.1.x) and after migrate the database.

Please send me a step by step description the lighter and/or better solution.

Thank you!
