Changing relationship cardinality on the existing data

[Nallapati, Sreenivasulu]

Hello,


We want to change the cardinality of a relationship from 'SINGLE' to 'SET'



When we tried to update the relationship cardinality it’s not allowing with the 
below error.

{

  "errorCode": "ATLAS-400-00-038",

  "errorMessage": "invalid update for relationshipDef dataset_to_schema: new 
end2 AtlasRelationshipEndDef{type='schema', name==>'residesIn', 
description==>'null', isContainer==>'false', cardinality==>'SET', 
isLegacyAttribute==>'false'}, existing end2 
AtlasRelationshipEndDef{type='schema', name==>'residesIn', 
description==>'null', isContainer==>'false', cardinality==>'SINGLE', 
isLegacyAttribute==>'false'}"

}





Is there a cleaner way of updating the relationship cardinality without 
cleaning up data/recreating the models?


Please suggest if there is way to make it happen.
