Is it ok to change Sold To on SO before Sales Update?

I have an sales order that made it through invoicing to next status 620 that was coded to the incorrect sold to address number.

The person running the invoice, instead of correcting it in E1, created a manual invoice and changed the customer name before sending out.

The order was placed on hold to prevent sales update.  Would it be ok to update the order in E1 for the correct customer number before running sales update?  Would this cause any issues?  Otherwise I suppose the order must go through sales update and a credit/rebook would be necessary. 

Thanks,

Brian
