Hi Prashanth,
Thanks for the reply. We have the same requirement, where in the workflows keep on changing for every release and it is dificult to handle the versions.
We felt, Guvnor is not suitable option for this and started using local file system to acheive by creating multiple files with new and old process instances.
In your view is this correct or Guvnor is the best option?
Thanks
Mahi
