Hello, So I had our IT group upgrade my vault from 2014 to 2016 I went to check in the first model/drawing and everything looked fine. After I did the check in I revised the part and went to check in rev 2. When I did i noticed that it was highlighted in Red, it said that the vault version appeared to be a different document. I had our IT people stop and start the service and reboot the server but that did not fix it. I found that I can check something out of the vault into a directory on my hard drive and it looks fine for a check in, but if i check it into the vault and compare it it is Red and says its not the same document. This is the first time I have seen this problem but it only happens after i have check a part into the vault and go to check it in a second time.
