Anton, that's a good question and not an easy one to answer.
A lot of manuscripts that were copied were quite old and they would use an updated script style to copy. Also, something I've noticed and was confirmed recently by a historian is that they didn't pay much attention to line lengths (they didn't copy the exact width of the columns. Line endings could differ substantially from the exemplar.
But... I saw something recently that intrigued me... it was an early medieval manuscript and someone had added information and had used the old style of writing. I don't see that very often.
I also saw one recently that copied the old style of writing BUT the letters that have changed (like "r" and "a") were updated to the new style.
So... I guess there isn't one answer, but MOST of the time, as far as I can tell, if 15th-century scribes copied an early-14th-century manuscript, they would typically use 15th-century writing (styles changed quite a bit from 13th to 15th centuries). The illuminations sometimes changed a fair amount, as well. Same concept, but different drawing style and usually different clothing styles. Numbers were almost always updated to the newer styles.
