DCS 6.10 upgraded from DCS 6.9.3
There was a perpetual licence present in DCS Management Server before the upgrade to version 6.10, and the upgrade resulted in the DCS Management Server console being unable to read the formerly imported license.
To resolve the issue, please follow the steps below:
1. Perform a full backup of the SCSPDB database
2. Stop the DCS Management Server service
3. Execute the SQL query below:
delete from scspdb.dbo.[Settings.License] where scspdb.dbo.[Settings.License].rid != 0
4. Delete all licenses from the installedLicenses directory on DCS Management Server
{Drive}:\Program Files\Symantec\Symantec Data Center Security\Server\Management\installedLicenses
5. Start DCS Management Server service
6. Login to DCS console and import the license .slf files
