Re: Used 60D is unregisterable, unsupportable
Some years ago I bought a few fortigates from ebay. I believe some of the policies on fortinet's side may have changed since then to further dissuade people buying used equipment, but here's what I did.
When I booted it up, the previously registered owner was listed under the registration info in the dashboards. I bought it from a parts recycler, but the previous owner appeared to be a regional ISP. So it makes sense that the ISP would get rid of a bunch of older CPE through a third party.
I contacted support and explained the situation- I even mentioned the email address that appeared in the registration info. I simply wanted to transfer the ownership of the device into my "home" Fortinet support account so that I could attach it to forticloud and perhaps renew support. The Fortinet rep that responded was super helpful. The process was that they needed to reach out to the previous owner asking them to confirm the situation and to confirm that the device was not stolen or whatever. If the other party did not respond within 2 weeks, the device could be transferred to my account. The previous owner did not respond to their requests, so within about 3 weeks it was put onto my account.
