Can't upgrade to mautic 3.02 => 4.2 from command line

@vanguy765 Try do an incremental update using the command line where you install mautic from a zip file. Then run database migrations after each step. This will be tedious but it should get you to the latest version. Try not do a big jump in versions, as a lot changes and some file locations and or commands may not work.

remember to do each upgrade…incremental
Then database migrate
clear cache
next upgrade
etc

Hope this helps
