I have documentum server in the backend and sharepoint in the frontend/UI.

I am interested to use K2 black pearl to define workflow for the document management which could integrate sharepoint and document.

I would like to know how to integrate Documentum with K2 blackpearl workflow and how complex it would be?

If you have any previous experience in this kind of environment, please give us some light on this.

Thanks in advance.

As long as you can integrate to Documentum via APIs (COM+, .NET or Web Services), you should be able to integrate with it.

 In terms of complexity, I would think it depends on how complex your integration requirements are.  If it is just uploading and downloading documents, I would think it should be straightforward once you figured out the technical complexities.
