Viday, in the hue.ini, you should have a section that mentions the [oozie] > remote_data_dir.
You can perform a DistCP operation between HDFS clusters to copy Hue's workflow data over. You could even do DistCP as an oozie job.
However, it is likely you are running an individual Oozie Server in each environment, have different namenodes, and HDFS file paths for your data, so you will need to still edit your files. In which case, downloading your oozie workflow definitions locally, putting into source control, etc. then deploying where necessary would be more manageable.
