Is it possible to switch commerce engine?

Hi there! I'm new to VSF, and i'm looking for a solution that allow me to change commerge engine in the future.
For example, let's say I use VSF with a custom ui using the SAP integration.. is it possible in future to switch to Salesforce, without the need to change all the integrations, logics etc?

Let me know if the question it's no clear

Thank you very much!!
