[Koha] Update version

Hi All, I want to update my koha version 3.22 to version 17.11. Already install version 17.11. what is the process to update the version? In previous versions the process that was to download the new version and connect the database of the old version to the new version. Then enter the staff module to run the update process, is the process still the same? Thanks for your help, Ricardo ____________________________________________________________________
