Smart upgrade tab missing

Hi can anybody answer my queryI am testing the upgrade to release 8.02

I upgraded the server from 6.0.1 to 6.5.1 to 8.0.2

I upgraded my client notes, designer and administrator from 6.0.1 to 7.0.2 to 8.0.2

I have set up the Samart upgrade to upgrade the client on another PC. It works but only if selected manually.

I tried to set up a desktop policy document but the smart upgrade tab is not there.

Does anybody know why this might be.?

Thanks in advance.

Tricia.
