   > We test new versions of Superset by importing dashboards from our production Superset (currently in version 1.0) to our testing Superset (currently in version 1.3.2).
   > 
   > We were seeing the issues described here when importing dashboards into the testing Superset and just wanted to add that setting the `VERSIONED_EXPORT` flag to `True` in our testing Superset fixed our issue and now we can export and import dashboards.
   > 
   > Just adding this since this appears to be one of the first results when googling around, and having to turn on a feature flag may not be so intuitive. At least until #16569 is merged and the flag is turned on by default.
   
   I tried to solve the same problem with export/import but changing the `VERSIONED_EXPORT` flag to `True` didn't help me. I see the same error like below
   ```
   This Session's transaction has been rolled back due to a previous exception during flush. 
   To begin a new transaction with this Session, first issue Session.rollback(). 
   Original exception was: Dataset [reporting].[public].[lookup] already exists 
   ```
   I have Superset version 1.3.1
