Hi Michal,
Thanks for reaching out to the Adobe Stock community.
When you transfer your remaining Fotolia subscription downloads you get double your quota, meaning 2 Adobe Stock licenses for every single Fotolia download transferred.
If I understand correctly, you are looking to download half licenses from (the transferred licenses of Fotolia to Adobe Stock). Is that correct?
If yes, I would like to let you know that when you download a standard image from Adobe Stock, with each download one single license gets used up.
Also, the licenses which are transferred from Fotolia are valid until 365 days from the date it has been added to the user's account. Your licenses will expire on 11/16/2019. I would suggest you to download all your licenses within this time frame.
Note: The downloaded licenses always remain in the license history of Adobe Stock.
Hope this information helps!
Feel free to update this thread in case of any additional questions.
Regards,
Twarita
