I don't know of anything quite that direct.

https://community.kde.org/Frameworks/Porting_Notes is the best
reference, but you should also look at the kde-dev-scripts git
repository (part of our "KDE SDK" offerings), under the kf5/ directory,
where a bunch of auto-migration scripts can be found.

Easier to automate the migration to the extent possible, then use the
Porting_Notes wiki page to get guidance on the rest.  There will
undoubtedly still be a few mysteries to solve after that, especially if
you decide to also start migrating over to some of the new Qt5-based
features in the process.  But between those two resources you can get
most, if not all, of a working migration completed.
