There is no "KDE5"... ;-)

And as I already mentioned, Qt5 actually is quite compatible (to Qt4), porting 
applications from Qt4 to Qt5 usually only needs minor changes to the code, if 
any at all.
Porting kdelibs4 based applications to KDE Frameworks5 is usually not too 
difficult either, and there are extensive notes (and even scripts) that help 
with that.

It certainly is/can be a lot of work though depending on the size of the 
project.
(e.g. some things have been removed from the KDE Frameworks because the 
functionality has been moved to Qt itself, but that usually needs changes to 
the application code)

And as I wrote already as well, in the particular case of Amarok, some parts 
had to be rewritten because they used certain technology (Plasma, QtScript) 
that changed too much and/or has been deprecated.
That's not really the general case though. And many (most) other applications 
have been fully ported already anyway.

Kind Regards,
Wolfgang
