Did you perform the ARIS 9.6 installation on your own or by Global Consulting Services of Software AG?
If you have a simple ARIS installation, sitting on just one computer/VM, and created by ARIS Design/Connect Server setup, you could update that way again via setup. Of course, it's recommended to back up your data first. Please see the ARIS Server Installation and Administration Guide for details.
In case you have an ARIS installation, and it's spanning across several computers/VMs, which is a so called multi-node installation, then I recommend to ask your local sales representative for an offer by Global Consulting Services.
If you intend to do update on your own, please follow the instructions provided in the ARIS Update Cookbook (on the ARIS DVD and on Empower), but be aware what the disclaimer of that document states: You need profound knowledge to handle such an update.
