"iisftp.vbs" Is there an update switch?

I am using the "iiscnfg" command to copy the metabase from one server
to another but the problem is that the ftp IP on the remote server is
different. So once the command runs I need to set the FTP site to the
appropriate directory. I tried the following command but it creates a
new site with the same name. I just want to set the current ftp to the
appropriate IP address.

I used this to create a new ftp site.

cscript iisftp.vbs /create D:\FTPsite "InternalFTP" /i 192.168.1.14 /b
