Transfer a Structure (Tatara)

So I got a friend that wants to move a Tatara from one corp to another, he thinks that only way to do so is to unanchored it and reanchor it. I looked at the help articles (https://support.eveonline.com/hc/en-us/sections/201103521-Player-Owned-Structures) but those don’t seem to have anything on the transfer process. Google mostly shows stuff form before Upwell structures existed, so I think might be outdated. Anyone able to give the details on it before he pulls it up and sends everyone’s assets off to safety?

I’m pretty sure if the receiving Corp has “accept structure transfers” selected in their Corp settings, he doesn’t have to unanchor it.
