If you are migrating *to* Oracle, then you should probably ask this question in an Oracle forum.

Or is it the reading of the old data that is that slow?

But anyway: without a lot more information about *how* you do the migration nobody will be able to help you

Which program(s) do you use to migrate the data?
What type of connection do you have between the two servers?
What exactly is slow (inserting into Oracle, selecting from Postgres?)
