License Transfer

I have recently taken over a site from another firm. The transferred the license to me and I can log into the EE site and see the license in my company name. However when I log into EE on my site it still says ‘owned by old company’ at the bottom right of the admin screens.

Is there something I need to do to get that to change? The license change is only about 24 hours old at this time. Do I wait or do i need to import a new license key?

Thanks for any help in advance.
