I think I have to go through 5.1(3f), which is the "newest" version supporting upgrades from 5.1.2 and then go directly to 7.1(5).

Hi Christian,

The version you are running is in fact an ES (engineering special) as you nicely

noted You should be fine to move forward with your suggested upgrade path.

From the doc you linked;

Notes about Engineering Specials (ESs), Service Updates (SUs), and Windows Service Release (SR) Upgrades

If you run a Linux or Windows Engineering Special (ES), a Service Update (SU), or a Windows Service Release (SR) for any version listed in the "Direct upgrade" tables in the following Supported Cisco Unified Communications Manager Upgrades, you can also upgrade to the target version for that section.
