Acronis clone 500 GB SSD as 240 GB?

I am trying to clone a 240 GB SSD to a WD 500 GB SSD. Acronis partitions the 500 GB as an identical 240 GB drive and I get a second 240 GB partition that I cannot shrink or extend. I could shrink the main partition but I cannot extend it.

What should I do to be able to use the full 500 GB?

Sorry if my description does not use the right terms. I am no technical expert and English is am second language to me.
