title: Migration of database records from MySQL to PostgreSql (from 1 application to a revamped application)
body: <p>I have a question which I could not find a solution on google and stackoverflow. </p>
  
  <p>The situation is that I am building a new application(portal) which will replace the old portal. The old portal uses Mysql, which stores all the members' data. 
  Now I have to migrate all these members data to the new portal which is using psql. </p>
  
  <p>I searched everywhere and most tutorials are about converting a database from one database to another on the same application. But now I am trying to migrate just certain records from old application to a new application, and also changing the database from mysql to psql. </p>
  
  <p>Does anyone has any resources or tutorials on how I can achieve this? 
  Thank you very much. </p>
