The Run live preprocessing scripts task opens the Upgrade live preprocessing form and displays the scripts that will write prepared data into the shadow and dictionary tables that were created by the Initialize preprocessing task. After you run the live preprocessing scripts, you must correct any issues that are flagged with an error status in the grid. After you correct an issue, you must rerun the failed script, or all failed scripts, until all live preprocessing scripts finish without error. You cannot proceed to running the single-user mode preprocessing scripts until you resolve all live preprocessing script errors.
Run the live preprocessing scripts
Depending on the amount of data you are processing, running the live preprocessing scripts may take a long time. The scripts run while your Microsoft Dynamics AX source system is live and being used for production. This can slow system performance. To lessen the impact of preprocessing on your live system, you can pause some or all of the scripts during business hours and resume them after business hours.
Important
If you are upgrading from Microsoft Dynamics AX 4.0, the Microsoft Dynamics AX must be operating in the DAT company context for upgrade batch jobs to be picked up correctly.
