CRM workflow run another workflow

Not a duplicate of this

I have a pretty simple CRM workflow, which basicly just adds some values to some fields that doesn't get filled whenever a user creates a new开发者_如何学Python object. My challenge here is that a lot of objects are already created in CRM, with a lot of null values. We are talking thousands. So instead of asking the client to open every single object and running the workflow, I was thinking I could create a second workflow which initiates the first workflow to run on all current objects. Is this possible and how should I do it?

The problem is not the workflow execution. Its the selection of the record. Dynamics CRM doesn't have the possibility to execute a workflow against a massive amount of records.

You have to script a little program which selects the records for which you would like to run the workflow and start the workflow for each of them.
