I have the Document ID Service feature enabled in a Site Collection. I have a Records Center site provisioned in a different Site Collection - within the same web application. If I create a document in my first site collection, and then move it to the Records Center site, will it carry the Document ID assigned to it from the first site collection? Effectively, allowing me to search in Records Center using the document id originally assigned to it.
At the level of each Web Application there are 2 timer jobs which calculate and assign IDs to document, as follows:
You would need to make sure in your Records Center the feature for Document Id is activated too. Once set by the timer job the value is maintained as you move the document, this being actually the benefit of the this feature so users are always redirected to the newest location of the exact same document as the document gets moved.
