For example Azeris, Turkmens, Tajiks transitioning from the Arabic script, and Buryats from the Mongol script.
And why wasn’t there a cyrillisation of Georgian and Armenian?

But China didn’t feel the need to change the Uyghur Arabic script and the Mongol script and those ethnic groups in China still have high literacy rates.
China actually considered bringing Mongl Cyrillic to Inner Mongolia before the Sino-Soviet split
