Unfortunately that is not possible. This integration only works for the Netherlands and partly Belgium. Our Subway customers in the Netherlands use the software you have in Luxembourg and these are different from the ones in the Netherlands. If you want Integration with Yomani’s in Luxembourg then you need a new integration.
We have „Belgian“ and „Luxembourgish“ machines. The Belgian are from original worldline and the luxembourgish come from ex-Six payments. One of our customers uses the belgian variant and this should be the same.

Don’t forget to create a backup before installing new releases. You’ll need a working backup if you need to roll back to the previous version.
