Ruckus suggested code upgrade method

[MrGray]

A discussion in my office recently left me with some questions. I'm seeking guidance now. I've exclusively used manifest approach when code upgrading switches. I was told it do POE, code version, and boot (if needed for that model/code).
I'm hearing a few say that simply copying the image does all this as well. My gut reaction is that this is incorrect. I don't think Ruckus would include the POE firmware in the image AND put the raw files in the zip-folder, but I've been wrong before. I'm curious what Ruckus suggests as the best/preferred code upgrading method.
