I hope the move helps them and doesnt cause their products to suffer. We use Jira in my organization and I hope that we can eventually get off SVN and move to Stash or Bitbucket. Although thats probably a pipe dream but I still favor Git over SVN.
Just remember that until everyone is on board, you need strict discipline as SVN has a much small feature set the Git does. Thereby, you should read the git-svn documentation closely and not use any incompatible Git features. Good luck!
