filters are made for stuff like this. In your repo,

cat >.git/info/saved-connection <Server=prodServer;Database=myDataBase;
EOD

cat >.git/info/my-connection <Server=myprivateserver;Database=myDataBase;
EOD

git config filter.use-my-connection.smudge 'sed -f ".git/info/use-my-connection.smudge"'
git config filter.use-my-connection.clean  'sed -f ".git/info/use-my-connection.clean"'

cat >.git/info/use-my-connection.smudge    </ {
     w .git/info/saved-connection
     r .git/info/my-connection
     d
}
EOD

cat >.git/info/use-my-connection.clean     </ {
     w .git/info/my-connection
     r .git/info/saved-connection
     d
}
EOD

echo >> .git/info/attributes     path/to/app.config filter=use-my-connection
