Redeploying CRM4 from production to Dev environment

We followed the procedure outlined in this blog below and discovered 3 issues:

1. During the import database step on mapping the users, the Deployment Manager did not recognize and map users from the trusted domain
   
2. The import took hours for the 36 GB production database
   
3. Last but not least… J After the import no users could logging to redeployed environment getting "Invalid User Authorization" message – so re-deployment was not successful.
   

After repeating the procedure while having the Update Rollup 8 installed, all problems went away, and the Import process took 10 min instead of hours.
