How to transfer the single licensed ms-office license from old system to new system.

Hi,

It seems you have Office installed on your old system and now need to migrate it to a new one? It is easy but not supported in this forum, in our forum we mainly discuss technical questions and feedbacks, we don't have access to your licensing status.

For your question, I suggest you contact the local customer service, which is the best portal for your scenario:
