Can we bulk edit labels on Idea Exchange threads?

[JoeMayall]

We're changing the labels on our Ideas Exchange, and would like to find a way to bulk edit the already existing threads to the new labels.

For example, there are a lot of threads that have the label "Company." This label will be changed to "Companies." Is there a way to edit all of the threads that have the "Company" labels to be "Companies"? 

thanks!

I now have working scripts to change labels in bulk and to move posts in bulk if anyone is interested.   Message me with your email address.
