Change plan or/and renew plan period

[elephantux]

How do I change the plan for a user who already has an active plan and have the expiration dates updated based on the data from the new plan?

Everything is changing and updating with changePlan($plan) method except for the starts_at & ends_at dates.

My solution:

$user->subscription()->changePlan($plan);
$user->subscription()->update([
    'starts_at' => null,
    'ends_at' => null
]);
$user->subscription()->renew();

But I don't think that's the right or best solution.
