Force reinstallation of all packages installed from ports-2012 (gentoo)?

Question

I asked about a problem with upgrade to meta repo here:

I got most of the things to work now, but the following issue of ebuild source conflicts keeps bugging me:

# emerge -av "=dev-qt/qtwebengine-5.9.2:5/5.9::kde-kit" "=dev-qt/qtgui-5.9.2:5/5.9::kde-kit" "=dev-qt/qtwidgets-5.9.2:5/5.9::kde-kit"                                                                                                                                                                           !3940
Password:
!!! Repository 'x-portage' is missing masters attribute in '/usr/local/portage/metadata/layout.conf'
!!! Set 'masters = core-kit' in this file for future compatibility

 * IMPORTANT: config file '/etc/portage/package.use' needs updating.
 * See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS
 * sections of the emerge man page to learn how to update config files.

These are the packages that would be merged, in order:

How do I force reinstallation of all packages that were installed from the old repo?

Found it!

The trick is "# emerge -auDN --newrepo @world". The '--newrepo' option is crucial.

Update 19 Oct 2017:

The command above works for more than 1000 packages I have installed, except the qt* packages. For these stubborn qt* packages I had to do the following:

emerge -Cav "dev-qt/qt*" 
 * This action can remove important packages! In order to be safer, use        
 * `emerge -pv --depclean <atom>` to check for reverse dependencies before              
 * removing packages.

>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed.

Would you like to unmerge these packages? [Yes/No] Yes

Next, run this command:
 

# Here I have renamed the /usr/portage directory for backup
emerge -av @preserved-rebuild
