I have a MySql Database for the previous version of my application, now The application is rebuilt with a somewhat different data model and using Oracle DB.
I want to migrate data and pictures from the old database to new Database, When I search for this topic Oracle recommends using Sql Developer and has some tutorials about it but I am not sure that's what I really need. I think these tools and procedures are for "creating" a new database model when you give your existing model. But I already have a second database with different mappings and data model etc. How can I migrate data in this case, is this all need to be done manually by sql scripts?
Actually I need an action plan to start, at the moment I'm stuck with no clue
I have the dump of previous database
