I want to update every deal i have that has a stage of X to a stage of Y.  After using zoho for a while i realize i have some duplicate/unnecessary stages in the system.  What is the best way to go about doing this?  If i go to deals and tried to select 100 at a time and do mass update, it's not an option.  Would I have to write a deluge script to do this?

I have about 2,000 deals with this stage.
