Hello,
I am trying to determine if your documentation will work for a swing migration from 1 SBS 2011 to a new hardware / software installation?
No, we don't have such a guide. SBS 2011 is out of support soon so migrating this to new hardware is not a good choice. You should migrate to a modern, virtualized environment with Windows Server 2016 + Exchange Server 2016 if you want to use the Essentials Role or to the 2019 versions without the Essentials role.
If you really need to migrate your SBS 2011 to new hardware I would do this Virtualize your SBS 2008 or 2011 and run it as a virtual machine on Hyper-V server
