Since I do want to change two segments instead of one to later date, it is not possible through the website. IST-Europe segment is not upgraded with voucher due to the lenght of IST layover but now when trying to change the date, it goes to J and TK asks 4 digit euros to pay just for IST-Europe upgrade
.
Sent the chosed flights to TK contact, will be done on the next week since today is Friday. Recommendation is to contact local office and wait, it takes time and the weekend is coming.
Update: Both flights were changed as I wanted, a few days later without IST stop. Now also the second flight(IST-Europe) is in business class, J- business upgrade as per booking.
At first, now expired upgrade voucher was removed from booking, new flights were booked to economy and upgraded with re-issued voucher. Regular(not corporate) multi city ticket, smooth process as always from TK designated contact.
