I wouldn't try to install a 9.4.x UCS on a 10.x unit as it will probably be difficult to resolve the issues with loading the full configuration. You might do better trying the SCF file or more ideally, just try loading the bigip_base.conf and bigip.conf from 9.4.4 on the 10.x unit. Of course, the cleanest solution is to install the same 9.4.4 OS version on the new platform (assuming it's supported on the new platform) and then upgrade the OS. The configuration will be upgraded to the new syntax in the process.
