Dear All<br />
<br />
I have never upgraded synology NAS before, so I would like to ask before I go ahead to upgrade.<br />
I would like to upgrade to latest DSM 4.2 from 2.3. Is it possible?<br />
<br />
If it is not possible, what firmware in between should I upgrade to??<br />
Generally, I would like to double confirm that my data (files) are safe during &amp;&nbsp;after upgrade.<br />
<br />
Thank you in advance for your help.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
