Overwrite/Delete Existing Static NAT Entry

I have an old webserver (w2) that is being replaced by a group of webservers (w3, w4, w7, w8).

On my ASA the External Web Address for website "A" is mapped to the old web server.  
Ex:
static (dmz, outside) 67.x.x.x 10.x.x.x netmask 255.255.255.255

I need to change the internal address (in bold) to the new web server 10.y.y.y.

When I enter the changes into the ASA, of course, it returns an
Error-Mapped Address Conflict With Existing Static

As these sites are moved to the new servers (a gradual process) I'll need to continue to update these entries.  

How do I do this?

Thank you!

What version of code are you running on your ASA?

Remove the 10.x.x.x first:

no static (dmz, outside) 67.x.x.x 10.x.x.x netmask 255.255.255.255
static (dmz, outside) 67.x.x.x 10.y.y.y netmask 255.255.255.255

...or log in to the ASA using ASDM and just edit the NAT rule.

You'll also need to edit the associated Access Rule to allow the traffic through the firewall, but I'm sure no-one else forgot that ;-)
