Question

I have an existing website built on ASP.NET + SQL SERVER. It should move to Django + mysql soon.

What is the best practice to create the new MySql DB? I would like to keep some Unique IDS because they affect the URLS that should remain the same after the transfer.

Also I want to avoid the option to inspect database with Django because many models will be changed somehow.

Answer 1

If this was my site I will follow this steps:

1. Create the new CDM (Conceptual Data Model) of the new database
2. Create django models that will catch with new CDM.
3. With SSIS, migrate SQL Server Database to MySQL. (Relax some restrictions and constraints if it is needed)
4. Add relaxed restrictions and constraints to new database (auto_increment columns).
5. Enjoy
