I messed up.
I upgraded a machine (11.3 5887 HF2) with an Opal compliant drive to Windows 10 1909 (from 1809) without decrypting/uninstalling first as is recommended.
Now, the computer boots fine with no preboot but the Symantec Drive Encryption Service will not start. I cannot get the SEE Client Administrator to open which fails with a .NET error on SEEaAdminUIApp.exe.
If I boot to recovery, it says it cannot initialize the drive but when I do a --recover-disk it says the disk is already instrumented and recovery is not necessary.
The client does check into the console, although I don't seem to be able to issue a successful decrypt command to it.
I tried to roll back to 1809 which was successful but no change in behavior.
So three questions:
1. How do I get out of this? :)
2. Is it typically a hard and fast rule to decrypt/uninstall with Opal drives?
3. I see Windows 10 1909 support is "officially" enabled with 11.3 MP1 HF2. Does anything think this is the actual problem and *not* the fact that I upgraded an encrypted Opal?
This is just a test machine so at least that's something ...
Thanks in advance!
