Sorry but can you please elaborate what are you actually looking for?
Tool integration? Check with Oracle or Informatica.
we are planning to migrate mappings from the informatica environment, and transfer them to ODI. is there a way to do that? or are we just going to build again from scratch if we want to have mappings in ODI?
Do you mean the migration from biapps 796x series(Informatica) to biapps 11g series(ODI).
If you meant so, then as of now there is no any migration available from INFA to ODI, as you got to wait for the next 12 months from oracle. Inturn, after 12 months u can have biapps 11g with Informatica adapters same like biapps 11g with odi adapters.
As far as my concern, u got to consult ORACLE for the promising answers.
