I have had been able to take a few WordPress sites to Kentico. It was not as hard as you think. Using a good export tool that will allow you to get the page content out to a Pipe Delimited file was step 1. Then import data into SQL server to do some bulk clean up. Use the very powerful Kentico Import Manager and SQL Query to import structure to mimic the folder structure of the old site. Then import the BLOG POST under that structure using a dynamic node value to place the items in the right place.
All WordPress Pages then were imported as SIMPLE template pages.
The last site I did was 1500 blog post. Took about 1 day of time, but the client is very happy. Before they had to make sure they did their Wordpress upgrades every week or they may get hacked. No more fighting overlapping plugins. YOAST Plugin has universally been the only complaint after going from WP to Kentico for business customers.
