-
-# Make the main steps to migrate an app to its fork.
-#
-# This helper has to be used for an app which needs to migrate to a new name or a new fork
-# (like owncloud to nextcloud or zerobin to privatebin).
-#
-# This helper will move the files of an app to its new name
-# or recreate the things it can't move.
-#
-# To specify which files it has to move, you have to create a "migration file", stored in ../conf
-# This file is a simple list of each file it has to move,
-# except that file names must reference the $app variable instead of the real name of the app,
-# and every instance-specific variables (like $domain).
-# $app is especially important because it's this variable which will be used to identify the old place and the new one for each file.
-#
-# If a database exists for this app, it will be dumped and then imported in a newly created database, with a new name and new user.
-# Don't forget you have to then apply these changes to application-specific settings (depends on the packaged application)
-#
-# Same things for an existing user, a new one will be created.
-# But the old one can't be removed unless it's not used. See below.
-#
-# If you have some dependencies for your app, it's possible to change the fake debian package which manages them.
-# You have to fill the $pkg_dependencies variable, and then a new fake package will be created and installed,
-# and the old one will be removed.
-# If you don't have a $pkg_dependencies variable, the helper can't know what the app dependencies are.
-#
-# The app settings.yml will be modified as follows:
-# - finalpath will be changed according to the new name (but only if the existing $final_path contains the old app name)
-# - The checksums of php-fpm and nginx config files will be updated too.
-# - If there is a $db_name value, it will be changed.
-# - And, of course, the ID will be changed to the new name too.
-#
-# Finally, the $app variable will take the value of the new name.
-# The helper will set the $migration_process variable to 1 if a migration has been successfully handled.
-#
-# You have to handle by yourself all the migrations not done by this helper, like configuration or special values in settings.yml
-# Also, at the end of the upgrade script, you have to add a post_migration script to handle all the things the helper can't do during YunoHost upgrade (mostly for permission reasons),
-# especially remove the old user, move some hooks and remove the old configuration directory
-# To launch this script, you have to move it elsewhere and start it after the upgrade script.
