To upload a newer version of an existing document or file in the repository, please perform the following steps:
Go to Collaboration>Documents. From the list of folders, choose the one that contains the file to be updated.
Once you have located the file in the folder(s), choose the manage button
Click the edit button beside the document/file to be updated
On the next screen, you should see the "Upload new version" button. Choose this button and locate the file to update.
It is very important to ensure that the naming convention for the new file remains the same as the pervious one. When a newer version is uploaded, the file simply overwrites the old one. Using a different naming convention may cause the link to the document to become invalid.
