You can use this option to get all the previous versions:

dgraph-io/badger/blob/8b89769ed71e56cf7f80abdcfd3576efc97bd412/iterator.go#L255


//
// This package provides DefaultIteratorOptions which contains options that
// should work for most applications. Consider using that as a starting point
// before customizing it for your own needs.
type IteratorOptions struct {
	// Indicates whether we should prefetch values during iteration and store them.
	PrefetchValues bool
	// How many KV pairs to prefetch while iterating. Valid only if PrefetchValues is true.
	PrefetchSize int
	Reverse      bool // Direction of iteration. False is forward, true is backward.
	AllVersions  bool // Fetch all valid versions of the same key.
}

// DefaultIteratorOptions contains default options when iterating over Badger key-value stores.
var DefaultIteratorOptions = IteratorOptions{
	PrefetchValues: true,
	PrefetchSize:   100,
	Reverse:        false,
	AllVersions:    false,
}
