upgrading to coreldraw x8

Maybe this is a stupid question. 

I've used X3 for the last 10 years very happily. I've just got a new laptop with win10 and I can't load x3 onto it.

I'm accepting that x3 is now obsolete and happy to buy x8 so that it will run on the laptop.

But, will i be able to simply open my old files created using x3 on the new x8? 

Can't seem to find an answer anywhere
