I am having a MantisBT version 2.19 and I would like to upgrade to the latest stable version 2.21.1. I have checked the manual and I think the upgrade chapter: https://www.mantisbt.org/docs/master/en ... grade.html is a bit confusing. First, it is asking to download and extract the latest version from within the webserver, then to put the website into maintenance mode and to run the /admin/install.php script from the already downloaded MantisBT which is only creating/updating the Database according to my opinion. It is missing to mention what to do with the extracted MantisBT directory after the upgrade is complete and also which URL for accessing it after the update. It fails to mention that you need to delete the
in order to get your bug tracker out of maintenance mode and how you can confirm that the upgrade/update went smoothly.mantis_offline.php
I have moved the directory to a backup directory and I have enabled in the
the/mantis/config/config_inc.php
but it is still showing me 2.19. So I guess I need to merge the new_bt directory with the old one. Am I right?$g_show_version = ON;
