The simple solution is this.
1. Save the document you are in.
2. Duplicate the document.
3. Navigate to the folder you had the original document in.
4. Save the duplicated document with the new file name, deleting the "copy 1" added to the original file name.
5. Select the original document.
6. Locate the versions menu using the tiny arrow at the top next to the name.
7. Select Browse All Versions.
8. Wait for the Star Wars floating stars background to appear.
9. Select the file image on the right side.
10. Navgate back in time by scolling, arrows or moving your cursor to the tiny time bars on the right edge.
11. Determine from this one tiny page at a time view which was the version when you opened the document.
12. Select that version of the document.
13. Close the original document.
You will now have achieved the same outcome as the old Save-As would have achieved. If you are on Mountain Lion then you have the Save-As function and you have to use that for steps 1-4 then you can start at step 5 here to create what Save-As used to do. I hope this helps you. If not there is another work around offered by user Yvan Koenig which is called the "get over it" solution. I am sure he will love to explain it to you.
