I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I'm not informatica expert but I work with it for Cognos.
Few things to consider before buying.
Why are you getting Informatica when you have datamanager (both can do ETL)?
Both are etl tools and if datamanager is sufficient for your current setup, no need to buy informatica.
However, informatica has more features than datamanager and if you want more ETL development that datamanager cannot handle, research on what informatica has over datamanager before purchasing.
Informatica can replace datamanager but there is a learning curve and different interface.
Also, you are paying for datamanager currently so it's best to use it if possible.

To evaluate informatica, wait for responses from informatica experts.
