WordPress plugins – “Update” in backend vs replacing all files with never version

Generally its all about replacing the files (old files are deleted, new files are unpacked)

The difference is:

Update throught the wordpress would / maight (depends if plugin is active or not, and if You run it from wp-admin/update-core.php or wp-admin/plugins.php site, and if it is bulk update or single)

  • turn on/off maintenance mode
  • create a lock file (to prevent parallel updates)
  • silent deactivate / activate plugin
