Re:Manual upgrade H.C 6.1 to 8.X issue
This message shows that HC8 panel is not configured correctly, after the installation you have to configure panel with following setting.
o Server Roles should be same as in HC6.1.
o Webspace Root Path and other third party applications (DNS, FTP, Stats, Mail, Scripting etc ) should be same as it was in HC6.1 and those can be enabled at host admin level at this path Server Manager---->Global Settings. You must add server in the cluster before moving further. Server can be added from Server Manager--->Add Server.
o Host Panel Settings (including Billing Configurations and My Server Configurations) should be configured properly before starting upgrade and those can be configured at host admin level at this path Server Manager---->Edit Server.
To make sure setting, try to create a test user/website etc.
