Is it possible to change the Organization name after the installation is over Or if a WBM migration has been completed to the server putting the object in that organization?

I think it is possible to change the Organization name after Windchill installation. But not sure how it is done. if possible, share the steps for doing so. It will really helpful for me. Also, i have one other question.

Suppose we install Windchill with an Organization name and then we migrate Objects to Containers present within this organization. Migration is successfully completed now. But now client wants to change the name of the organization name? Is this possible? if so, do we follow the same steps as the first scenario?
