@alireza-m Thank you for finding this!
But there is one possibility the version information would not get detected.
-> In case you add an existing and already connected redis resource to the resource manager - see https://github.com/alireza-m/zend-cache/blob/ede35a3dc6215decf88f23feaefac7438195e3cf/src/Storage/Adapter/RedisResourceManager.php#L337

The logic of this initialized flag is really strange on here and should be fixed.

But the $resource['version'] can be set only once.
