One of my client is requesting a upgrade for his existing voice infrastructure, he needs to keep the same hardware but need to change the version from 6.1(2) to 9.1(1), the existing paltform is MCS 7816 H3. Upone the documentation this is feasible by adding memory and harddisk and it will not be direct it should scale from 6.1(2) to 8.0(2) and then from 8.0(2) to 9.1(1).

Is this the correct path to do this upgrade?

Shall i buy the upgrade package for 9.1(1) only?

The compatibility doc is up to date, phones like the 7940 which are already EOS/EOL are not tested and therefore do not show up.

You're still able to configure them, and use the features they had with the last FW release, any kind of problem that is determined to be related to the phone itself or its FW, will not be addressed by Cisco.
