composer require league/flysystem-replicate-adapter
ReplicateAdapter facilitates smooth transitions between adapters, allowing an application to stay functional and migrate its files from one adapter to another. The adapter takes two other adapters, a source and a replica. Every change is delegated to both adapters, while all the read operations are passed onto the source only.
$source = new League\Flysystem\AwsS3V3\AwsS3Adapter(...); $replica = new League\Flysystem\Adapter\Local(...); $adapter = new League\Flysystem\Replicate\ReplicateAdapter($source, $replica);
