Update from 26.0.1 to 26.3 with OCLP Nightly?

Hi,

a friend of mine accidentally updated his iMac 18,3 (2017) to Tahoe 26.0.1.
With the help of a nightly version of OCLP, I was able to get it working again, and for the moment it is running so well that he can work with it quite good. He doesn't need wifi, for sound he is using an external speaker and mouse and keyboard also work without any issues via bluetooth as far as I know.

My question is, can he update without any issues to Tahoe 26.3?
Has anyone maybe tested this yet and can report?

P.S.: The version I used, should be this one, built on 2025-07-21: https://github.com/dortania/OpenCore-Legacy-Patcher/actions/runs/16423650721
