You cannot go directly from v8.6 to v11d
What you could try is
shut down all BackupExec services
copy the entire c:\programme\veritas\backup exec folder to a workstation
install v8.6 in demo mode to the same path
upgrade that to v9.1
then upgrade that to v11d
shut down all Backup Exec services
copy the c:\programme\veritas\backup exec directory to your W2K3 server
install v11d on top of the copied directory
Not sure if this will work, but it's al that I can think of.
