Change Starting Order Number in ASPDNSF

From within your storefront’s “Run SQL” option under “Configuration” | “Advanced” (or from within SQL Mangler, I mean Manager, enter the following command:

dbcc checkident(OrderNumbers, reseed, XXXXXX)

Where XXXXXX is the new number you want to use as your seed.

This can come in very handy if you moving from one storefront to another to ensure a continuity of orders.
