Hello Jasmin, 
 
 Thank for the update .. 
 Just to update you, 
 we have initiated the remote session at the client side & found that the host-name was incorrect,hence recovery not happen. 
 
 After recovery once the system is restart/shutdown , 
 the system is locked again & again we need to perform C/R from SGN Center for user/other login on the client side. 
 
 Also at our client side two safeguard console is having like 6.1 and 8.1, 
 The IT engineer uninstalled the packages as below sequences: 
 1.Uninstall Client Configuration 
 2.Uninstall client 
 3.Uninstall Preinstall Package 
 and finally removes the old 6.1 console certificates. 
 
 Then install the new client as below sequence: 
 1.Install Preinstall 8.0.251 
 2.Client 8.0.251 
 3.Configuration 8.10.0.323 
 and update the new certificate of 8.1 console. 
 
 Client is migrating the old endpoint which is on SGN 6.1 to SGN 8.1 here & feature we uses in the latest is as below: 
 
 Do we need to remove the host entry from the sophos 6.1 console,if yes then share the procedure and how we can cross verify in the old 6.1 SGN console. 
 [Note : this issue is reoccur in some system like win 7 Sp1 ,win 10;etc ] 
 We need your help in the above scenario & suggest for the same. 
 Thanks. 
 
 Warmest Regards, 
 Paresh.

Hi paresh palav 
 If the user's password has been changed from the Active Directory, Safeguard client may ask you about the old password to sync the older user certificates when he tries to log into the system where Safeguard client is installed. In that scenario, please refer this article to get the steps what can be performed when this issue arises. 
 Also when you are changing the name of the machine, please make sure that machine client synchronization has been done once before rebooting the computer.
