If individual vouchers were already sold before using the Gift Voucher plugin, e.g. generated via another plugin or an external ERP system, these vouchers usually need to be migrated. For this purpose, there's an additional option to manually generate vouchers. The following steps must be observed:
Create gift voucher products for all desired voucher values as described here.
Open the vouchers in the voucher administration, switch to the Individual voucher codes tab and click on Generate new codes there.
Enter the desired number of vouchers for the selected voucher value and click on Generate.
The vouchers can be downloaded and printed directly, or selected at a later time and printed as a PDF. Alternatively, you can download all selected voucher codes as a CSV file using the Download Codes button.
The Note column can be used, for example, to record the voucher code of the migrated (old) voucher, to ensure that old vouchers aren't accidentally reissued multiple times by mistake.
