Hi @BLLBrucemo,

IFS runs with Oracle database and there is no way around that. IFS business logic is written in PL/SQL so the application is heavily reliant on Oracle database. 

By “SQL db”, I assume you mean Microsoft SQL Server. It is used for additional installation options such as SSRS, but not used as the main storage tier. 

You can find storage tier documentation here:

Hope this helps!
