WebMethods 6.1 upgrade paths?

I have recently inherited a system that is using Web Methods 6.1 Broker and Integration server running on Windows 2000 server, is their an upgrade path to a newer version of software?

Thanks

You have to do 2 phase side -by-side migration, i.e 6.1 -> 7.1.3 and then 7.1.3 - > 9.0 . You have to even change your OS as windows 2000 is not supported by 9.0.
