Secure IP

Any info is greatly appreciated.

I added a unique IP, and associated it to a domain - but I need to change the domain that I associated to, and associate it to a new domain name.

I’m not sure how to do that on the control panel. Do I deactive the secure domain? Will that deactive my site, or just the unique IP, and can I re-associate the unique IP to a new domain?

I get this message:
This domain is presently providing either anonymous FTP or secure web service, both of which require a unique IP. If you would like to disassociate this IP with the domain, you first need to disable those services from the Manage panel.

But I don’t find a disable button. Do you think it’s the same as “deactivate”?
