After upgraded from Couchbase 2.1.1 CE to 3.0.2 EE directly in Windows 2008 R2 64bit by installing 3.0.2 EE windows amd 64.exe, all things are fine but Views seem not work as normal

Hi Sir, We have upgraded from Couchbase 2.1.1 CE to 3.0.2 EE directly in Windows 2008 R2 64bit by installing 3.0.2 EE windows amd 64.exe, all things are fine but Views seem not work as normal. We found a critical View cannot return all stored document until we "rebuild" the index in following steps: made a bit different definition to the original view and save it, let's call it a New View. publish the New View recovery the view to its original definition publish the original view again After go through the steps above, all documents are returned. Since we have a lot of Views, manually rebuild each of them does not make sense. Please advise how to fix this, any idea would be much appreciated.
