If you did not mark the Save Old Address in Constituent Address List checkbox on the Process Options tab, just rerun it.
If you marked the Save Old Address in Constituent Address List checkbox on the Process Options tab, restore to a back-up (BB52243) first. Then rerun it. If you do not restore to a backup first, you will have duplicate addresses on the Addresses tab because the process starts from the beginning. Whoever was already processed already had the old address saved. When they are reprocessed, the old address is saved again as a separate address.
