Can the DAT be supplemented for the OAT?

Hello everyone!!!

I had two questions in regards to optometry school

1-I was wondering if schools would take the DAT instead of the OAT?
2-Is there any way to convert DAT scores for OAT? Like if someone, for example, has a 21 AA on the DAT, what would that convert to in regards to the OAT?

Thank you so much
