Thread:Project:Support desk/How do you change a category name

Hi There - I am trying to edit a category name within wikipedia further to a corporate name change that took place in Nov 2014. I am trying to rename the "Amaya Gaming Group" category to "Amaya Inc." and create a redirect so that if someone searched for "Amaya Gaming" that it redirects to the Amaya Inc.

Have searched the help files and not figuring it out...
