Moving domains to a new IP address

Maybe IP already used on a deactivated network card ?

-In Device manager take a look to the Hidden devices.
Remove hidden network card (that were previously installed)

What do you have when you IPConfig /all ?

The 97.74.x.x address is the IP address of the new server.

If I'm correct, I need to migrate my old domains to this new IP address in Plesk.

Your Network card has already 2 IP Address. So it seems you won't be able to use your "Ip Address Reconfiguration"  <-- Is this from your Plesk tool ? or another software ?

If another software...yes maybe you have to tell Plesk somewhere that it must now listen/work on this new adress.

Yes, this is a utility in Plesk:

I'm not trying to change the server's IP address, but rather the IP address associated with each domain.  I'm using the option:

"To map the selected IP address to another address, already existing on the network interface, select the Map to Existing IP Address option, and select the desired address."

I don't understand why the message says "Unable to map... such address already exists" when the whole purpose of this option is to select a existing address.

I can't see how the network card is mapped to both addresses, unless Plesk is doing this for me.  I did not modify the network settings in WIndows.

Yes sound weird....
" I can't see how the network card is mapped to both addresses"
In the properties of your network card, in TCP/IP you have a second tab : Alternative Configuration.
Other ip should be stored here...
If you did not configured it...sure Plesk did it...Have you launch this tool only once ?
Because launching it twice could explain what you are facing...and that would mean that what you want is already ok.

How do you know that you are done ?

Nice you solve it  !!!

You are welcome. I didn't feel really helpful !
