IMS is a hierarchical database, not relational. It is also quite old
technology. I doubt Oracle will have any conversion tools for that. I
started my career working with IMS DB/DC in the late 70's. You will really
need to design a new database from scratch and then convert and import data.
I did several conversions from IMS to Oracle in the late 80's. You will
have all the traditional challenges of going from a non-relational database
with repeating fields, etc.
What's the front-end? I assume that will need to be rewritten as well. The
most common front-end for IMS was COBOL programs running under IMS/DC or
CICS.
If you have access to DB2, I know IBM had tools to convert from IMS to DB2.
And I believe Oracle has tools to convert from DB2 to Oracle. So that's a
potential option. But with any conversion tools, you will have to
compromise with a good database design.
