I hear and feel your pain.

When we switched to PRI's earlier this year we did it in steps.

1. Get the PRI's idling. The turned out to be a nightmare. The company doing the work was purchased by Avaya so I had to figure this out for myself!!!! Now it's a piece of cake ;)
2. Try routing outbound calls over the PRI.
3. Move only one range of DID #'s to PRI, pick a range that doesn't include important people, if possible.
4. Move the rest of the DID ranges.
5. Wait a couple months then disconnect old copper trunks.

Yes it takes longer to do this in stages but it was necessary to have minimal, if any, down time!
