Preparing to install Lion

Hi,

My Mac is running OSX 10.6.8 with Symantec Antivirus 10.2 which is not compatible with Lion.

I want to install Lion and I understand that that Norton Antivirus 12 supports that.

 

What's the best approach? Should I be uninstalling 10.2 before I upgrade?

Is there a working procedure for this publishe somewhere?

 

Thanks
