Hi there, 
You can run delta migration multiple times. You can learn more about the Delta migration feature via this article. However, please note:

• If in the first migration, you did not enable Keep Original IDs setting (as noted in this article), you can continue the delta migration as normal.
• If you did enable Keep Original IDs, then you need to delete your testing data, otherwise, it might lead to ID conflict issue.

We hope that helps.
