Assuming V1 and V2 offer users the same functionality, there’s a bunch of tests you can offer. The best one IMO is oracle testing where you do something on v1 and v2 and check they do the same thing. Preferably roll out to a subset of users such as via a canary deployment and make sure you have a rollback plan.
