Are Sketchup 2015 pro files usable in Sketchup 2020 pro

I would like to take the pro 2020 version of sketch up. But I would like to know if all the files of my 2015 pro version would be usable on this version. And how else to convert them to PDF. when it’s plans.
Thank you for your answers

Hello, any version of SketchUp is fully able to open previous SketchUp version files. Also, any pro version can export to PDF. You then won’t encounter any compatibility issue by upgrading

Hello thank you for the information.
