When your files have expiry dates, such as certificates, you should Add a New Version when it renews and NOT simply just use the Add a New File option. This will mean the latest version is automatically associated to the original file and therefore, makes it easier for audit and traceability purposes. Another added bonus is that it will keep your Files section tidier, reducing the amount of expired files needlessly displaying, as they will be neatly stored within the file's History.
To see how this works, follow these steps:
Navigate to Files:
The list of files you have added (or have had shared with you) will display; find the one you need to update and put a tick in its checkbox (Please note: You can only add new versions to files that you uploaded):
Ticking the checkbox changes the list of actions available to you; select Add a New Version
Just like when you Add a New File, the same form displays, however most of the data fields are already populated, as it uses the same information as the original file.
You need to Upload the newest version of the file type and update when it Expires.
When all updates have been made, press Save.
The file will upload and the Version History page will display your current version at the top and show previous versions in the lower section:
Remember that files only need to be uploaded once, as once they are stored within the system they can be attached to any tasks by selecting the attach existing files option, described in more detail in GLSA - Completing Tasks.
