Duplicate data in columns

Hello,

 

I'm trying to migrate an input MySQL "user" table to the output PostgreSQL table "users" . There are 2 rows with the same e-mails as in the input and output column "e-mail". In my case I want to keep (do not overwrite) this 2 rows in the output table and migrate everything else except these 2 lines.

Is there any scenario or any solution to handle that?

Thank you.

Sorry for my English.

Hello Manohar,

know my job looks:

 

MysqliNPUT>>tConvertType>>tMap>>tUniqueRow>>PostgreSQLOutput>>tLogRow

 

But I still can't avoid an error for duplicate key value email: in output table email: xxx@xxx.xx allready exist....

Can I migrate only data wich are not duplicate?

Thank you in advance.
