   ### Search before asking
   
   - [X] I had searched in the [issues](https://github.com/apache/incubator-devlake/issues?q=is%3Aissue) and found no similar feature requirement.
   
   
   ### Description
   
   most of time
   when we want to migration a table. we use the flow step.
   1. rename TABLE to TEMP  (stop if error, define `defer` to rename back on error)
   2. create new TABLE (stop if error, define `defer` to drop TABLE on error)
   3. convert data from TEMP to TABLE (stop if error)
   4. drop TEMP.
   It‘s better to create one helper function to do it.
