Yes. But as someone that's been meaning to switch off of Evernote - never has a project bloated their own software with so many unasked for features / desperate attempts to grow valuation - it's a non-trivial project. One needs to have a high degree of trust in the import tool and new repository.
While it's not perfect, I like Evernote and its new incarnation. Feature parity between platforms is what saved it for me, and use almost all of the features they offer. I was getting ready to leave it for good. Nevertheless, I don't expect everyone to share the same sentiment.
On the other hand, you don't need to import anywhere at first. Just convert your files to Markdown, put the files aside and create your local knowledge base. You can import these Markdown files to somewhere new when you find the correct place, why not?
This is what keeps me at Evernote most. I can just move out in 2-3 hours, or in half day if I want.
Did they finally add exports bigger than 50 items to the new app? Last I checked, you still had to install the old one for a full export, and I don't expect it will work forever.
The help doc says there's still a 50-note limit doing it from the note list, but they did finally add a full notebook export. Maybe I'll give it another try.
