Can we change item number on Maintenance asset

Summary:

Can we change the item number of an asset in Maintenance Cloud?

It seems this is only possible when there are no work orders linked to the asset. In our case, we have assets with existing work orders, and the item number field is not editable on the Manage Asset page.

Is there any other way to update the item number for these assets? If yes, what impact would it have?

Thanks,
Umer
