Is it possible to import site template in DNN Platform 8.0?

We have internal Evoq Content 8.1 that we would like downgraded to free (community DNN) version. Downgrading the site seems to be possible but very labor intensive opening a lots of troubleshooting opportunities.

Another approach would be starting from clean DNN Platform installation and then importing the existing site, but it looks only the newest version 9.1.1 has that option. Not sure why is that so because it does not make sense to have export option if you cannot import.
Thanks in advance!
