New MBP set up - restore from time machine

My old MacBook (mid 2007) running Snow Leopard has died. I just got a new MBP Retina running Yosemite.

Now, I have a few question that I googled for answers, but I am confused. I would appreciate any help, guide, orientation.

(1) Will I have problems restoring from Time Machine, created on a Snow Leopard, to a new MBP running Yosemite?

(2) Should I say yes when the set up assistant ask me to "restore from a back up"?

My goal is to have all the files, apps, and configuration from my old Mac into the new one keeping the new OS.

Is that possible?

Thanks in advance for your help.

Vero.
