Who suggested/asked you to do the migration this way? Do you have any idea on how much data issues can be introduced this way? There was/is a reason why Primary key & Foreign keys are defined. I would not suggest you to do this way at all.

Instead try:
1. Have a look at the database design properly. make a list of tables in a sequence where the lowest tables having maximum dependencies and top once being kind of master table with only primary keys.
2. Populate/Migrate the table from top to bottom order - First the master tables and then the dependent tables.

This way you wont need to drop any key and the data would have least chance of getting corrupt.

I would suggest you to talk to your senior and get more guidance in case you need more help on the same.

It is generally a bad idea to do this, but sometimes you need to do it for bulk inserts.

You can disable constraint checking, see here :
