Advice- switching voo from moomoo to cspx in fsmone

I only started DCAing into VOO via Moomoo for about a year and have about 2 shares now. I paused my RSP and planning to start DCAing into CSPX via FSMone - just planning ahead for witholding tax & estate tax.
What should I do with my VOO - should i switch in now to consolidate or just hold and let it compound quietly? Thinking about the costs of switching in now vs the dividend tax drag. Not sure what’s the best move
