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

I look after a small enterprise with SonicWALL TZ devices.

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.

I now want to update a TZ205, in a remote branch. When I  log in as me, all I can see is firmware for the TZ215, the file I downloaded is called  "sw_tz-215__eng_5.9.1.1" The release notes mention and discuss a heap of different SonicWALL devices.

Is this firmware the same for a TZ205?  What will happen if I try to reflash the device?

No, typically there is a unique download/update for each model of Sonicwall.

Sonicwall only lets you see/access the ones that you have paid for on support.

My guess is if you try to install the wrong one it will stop you at the outset.
