HP Data protector Express 6.0 Devices offline

Hi
I have HP Data protector Express 6.0 its 10 seat license. Recently we had to change our IPs to different subnet at work. Now all other server shows devices offline, Host server IP has updated to the new address, but when I click on devices it shows the old ips. All those drives has yellow mark, I rescan the device/ stop and start services still shows offline.

Can someone point me to right direction please where to update the IPs on the clients and how to bring those clients online?

Thanks
