- New name : switch_space_id.
- The given space id is checked in application.properties.
- Most of the treatments have been moved to a "components" folder,
allowing us to create easily a new "migrate_several_projects" (or
"bulk_project_migration") later.
- The workflow can be launched from the single project view on the nG6
website, when logged a superadmin user.
- The project's space_id is visible to everyone on the single project
view.
- A warning indicating that the migration updates the retention has been
added to the workflow's form in single project view.
- More logs in ng6.log, and the new log file MoveProject.stdout. (path
exemple : [...]/jflow/work/switchspaceid/wf000452/MoveProject_default/MoveProject.stdout)
- CSS updates for the project views.
- For new space_ids, the <space_id>/run and <space_id>/analyze
directories will be created if missing.
