[aur-general] Best Practice for switching packages from svn to git

Hey everybody, I'm in the situation that one of my packages switched their VCS from SVN to Git. Is it okay to conflict both the non-SVN and the SVN package at the same time? The package in question is nagstamon-svn, whose upstream made the change to Git. I want to use the following lines in the PKGBUILD: provides=('nagstamon') conflicts=('nagstamon' 'nagstamon-svn'). Any opinions towards this? Greetings, Christoph
