can we change JIRA workflow scheme using groovy?

[srinivasp]

We are planning to introduce new issue types which includes epic and story types to existing issue types. So I have created a new scheme copied from the existing scheme and added epic and story and associated all the projects but there is no option to directly association the new workflow scheme to all the projects. So i am thinking of writing groovy to associate this new scheme for all the projects? Is this a right approach? Please suggest.

JIRA Command Line Interface has updateProject which will change the workflow scheme provided issue migration is not required. This can be use with something like

jira --action runFromProjectList --common "--action updateProject --project @project@ --workflowScheme xxx"
