downgrade 8.1.7.2 to 8.1.6

I have an 8.1.7.2 database which I know for sure containing no features above 8.0.6 because I just upgrade it from 8.0.6 to 8.1.7.2 a few days ago.
I need to bring this db back to our development srv which run on 8.1.6. I have clone the 8.1.7.2 db to our 8.1.6 development srv. The 8.1.6 db seeems to work find. However, when I tried to do an export of this db, I received internal error msg and the export fail.

Should I downgrade this db even if it is now running fine on 8.1.6? If I should downgrade it, can I run only the d0801060.sql script on this 8.1.6 development environment other than the 8.1.7.2 production srv? I wish someone can tell me the quickest way to take care of this issue? I hope I don't need to touch the production 8.1.7.2 db.

Any help is appreciated
