What about if I used a second "tool upload" tool? I took the python script from an earlier version and named it upload_old.py and did the same for the xml file (upload.xml -> upload_old.xml) while changing the latter to call the new python script. Nevertheless when I did that and tried to run it I got a popup window with the following error:

The Upload tool is a direct component of Galaxy. To use an earlier version of the tool, I believe that you would have to run an earlier version of Galaxy. 

Others here can amend this, if they know of an alternative.

Hello everyone,

I was wondering whether it's possible to downgrade the upload tool to the previous version(1.1.4).

I copied the upload.py and upload.xml scripts from a previous galaxy version to the tools/data_source/ directory and reloaded the tool as admin but it hasn't changed even when I restarted the server.

Do I have to change something else in addition?

Thank you,
