In this video I show you how to transfer the hard disks of your old QNAP NAS to a new QNAP NAS without any problems and without losing any data. I demonstrate step by step how to migrate the four hard disks of my QNAP TS-421 NAS in RAID 5 array to my new QNAP TS-664 NAS, while preserving all data and settings.

Hard disk migration between QNAP devices is quite possible, but there are important steps you should follow to ensure a smooth process. I will explain how to prepare your old NAS, deactivate the cache, check the firmware and finally insert the hard disks correctly into the new NAS.

You will also learn what preparations are necessary to successfully transfer apps, licenses and system settings without losing any data. Ideal for anyone who wants to upgrade or expand their old NAS!
