This upgrade was done with minimum downtime and maximum revert-ability in mind. All package building is done BEFORE the point of no return, so if there are any build problems, they will be discovered while the previous version is still running.

Back up previous mythtv packages

  • Package up existing mythtv in case you need to revert back: 
quickpkg media-tv/mythtv x11-themes/mythtv-themes
  • Package up mythtv plugins (Optional): 
quickpkg media-plugins/mythbrowser media-plugins/mythdvd media-plugins/mythgallery media-plugins/mythmusic media-plugins/mythvideo

Build new system

  cp MythTV-0.20-Overlay.tar.bz2 /usr/local/portage
  cd /usr/local/portage
  tar -xjf MythTV-0.20-Overlay.tar.bz2
  • Build the packages (but don't install yet): 
emerge -B mythtv

Install New System

  • Stop Mythbackend 
/etc/init.d/mythbackend stop
  • Back up database: 
mysqldump -u mythtv -p mythtv mythconverg > mythconverg-`date +%F`.sql
