Skilled Worker to Global Talent - dependent also requires switch?

Currently 2.5 years into a Skilled Worker visa. Discovered this week that my job role is eligible for a Global Talent visa, and was considering making the switch now so I could get Indefinite Leave by this summer.

My question pertains to implications for my dependent partner:

As my current Skilled Worker visa is valid until what would have been five years (August 2026), must my partner also switch his visa? Or is he allowed to stay on that Skilled Worker dependent visa until it expires (which is when he would be making his 5-year ILR application). It’s unclear to me if my changing category would invalidate his current dependent visa and require him also submitting for a Global Talent dependent.

Any and all insight very much appreciated.
