Hi, Gurbeer, CORB is great at such jobs: http://developer.marklogic.com/search?q=corb. Testing in a lower tier helps to validate the intended outcome and extrapolate how long the job is expected to take in prod. CORB is a Java process. You get to configure the number of threads. Tune it to utilize available system resources and shorten the maintenance window. Foremost, profile and optimize the code that will modify the documents -this isn't in response to your code, but just general guidance. Since this is a write op, this should probably be the only process that is writing to the database. And, as always, backup before you kick the job off and have a plan to rollback.
