Hi,
Yes this is ok. You will need to e-mail the details of the owner and the new owner, from the e-mail of the current owner, to support@capturesweden.com and we'll help you out with it. We need the name and e-mail of the new owner.
You can transfer the license to the new owner either way - and the new owner will be able to follow the upgrade path, yes. So it's entirely up to you.
