Good to hear!

The Installer in CentOS7 is confusing, particularly the partitioning
section, but it *does* let you do manual partitioning.  If you see
this display:

You need to pick 'I will configure partitioning'.

No one ever said it would allow you to upgrade the system in-place.
Aside from the 'preupg' method (which can leave you with a broken
system), the method you use to upgrade a system from CentOS6 to
CentOS7 is to back up your data, install CentOS7, and restore your
data. 

The jump from CentOS6 to CentOS7 is big enough that a lot of software
can't safely be upgraded via yum.  It's not a minor update.
