The current user flow is a bit odd:

1. Browse for the object
2. Open "Manage versions" (content/history)
3. Copy an archived object
4. Edit the draft
5. publish the draft

What we actually tried to do:

1. Browsed for the object
2. Opened "Manage versions" (content/history)
3. Opened an archived object to see if it is the right version
4. Tried to find any functionality for publishing this version

The edit page still needs some work on the layout to keep the functionality a bit more organized, but one new button would be good to have on this page when working on an archived object so that the user can re-publish the archied object with one click.
