Moving expired documents to another folder

Hi,

I'm new in SAP's world, and I already have the following scenario:

At the portal my team is developing, in the KM, we have folder structures of about 5 levels, and most of these folders are Timelife enabled. Up to here everything is fine.

But my problem happens when the documents, that are at these timelife enabled folders, expires, and I must move them to another structure of folders.

Firstly, a colleague told me to develop a Repository Service to do this. I found some code that almost do this, but didn't helped me so much.

After, talking to another guy, he suggested me to implement a "parallel" scheduler task. I found information about how to develop a task and schedule it at the portal (Did you know you can schedule jobs in portal using KM's Scheduler Task?).

Now, what's the way to navigate through a folder structure, check if the timelife is enabled, check which documents have expired and move them to another folder?

Thanks in advance,
