As carlmd cited, the firmware differs for each model. Get the support for the remote office transferred to you.<br />

Never tried seeing what happens if a different model's firmware is tried, but I doubt you really want to know.

I look after a small enterprise with SonicWALL TZ devices. <br />
<br />
The support company that initially installed them registered the devices to themselves. I had them transfer ownership of one, a TZ215 to me, so I can obtain support and firmware. <br />
<br />
I now want to update a TZ205, in a remote branch. When I &nbsp;log in as me, all I can see is firmware for the TZ215, the file I downloaded is called &nbsp;&quot;sw_tz-215__eng_5.9.1.1&quot; The release notes mention and discuss a heap of different SonicWALL devices. <br />
<br />
Is this firmware the same for a TZ205? &nbsp;What will happen if I try to reflash the device?

SonicWall TZ series, is the firmware the same across model?

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
