You wouldn't be importing it, you would be upgrading it. There weren't many differences between the two and the chances are it would work. I just opened a very simple 2019 project in 2017 and got no warning. However, I wouldn't risk it with a live project without a lot of testing and even then, one day you could do something that didn't play nicely cross version.
