Switching Data between phones

Hi, and thanks for any input in advance.

I have 2 android phones (Galaxy S10e and Vivo V20), both are updated to latest Android versions.

I'm looking to swap the data with each other. For example, transfer the S10e to Vivo and vice versa.

How would I do this? I've used the smart switch app before, but this would only work one way. Is there any way I can transfer both/swap the data between phones?

Thanks.
