I'm planning on upgrading from 9.5 SP5 to 10.1.2. I've read the upgrade instructions on the Customer Portal and they say to upgrade to 10.0 and then from there upgrade to 10.1.2. However, the PDF on the Customer Portal about the license update says I'd need to upgrade to 9.5.1 and then upgrade to 10.0. So I'm wondering which document is correct? Do I need to upgrade to 9.5.1 first?
