UTM to SG Migration

Question

We will be moving from a UTM appliance to an SG appliance. I have read some threads about migrating using an unencrypted backup on a flash drive. I just want to make sure I have all my ducks in a row before I proceed. 
 
 Update the SG to the same firmware as the UTM 
 Factory reset the SG 
 Backup the existing UTM (unencrypted), download it and copy it to the root of a USB stick 
 Plug the USB stick into the SG and power it on 
 
 Does the USB stick need to be formatted as FAT32? Does the UTM backup need to be renamed? Is there anything else that I am missing?

The new device can be Up2Dated to a newer version than the old device. 
 I have a slightly different process that results in only a few seconds of downtime: 
 1. Do a quick, temporary install so that the new device can download Up2Dates if needed. 2. Apply the desired Up2Dates (stop at 9.506 today) and do a factory reset. 3. On the current UTM in use, on the 'Hardware' tab of 'Interfaces', assign the MAC as the Virtual MAC for the NICs in use. 4. Create a backup and load it onto a USB memory stick. 5. Reboot the new device with the USB memory stick in place and remove the memory stick after the boot is complete. 6. Connect a PC to the new device, upload the license for the new device and then disconnect the PC, leaving the new device powered up. 7. Power down the old device and move the cables to the new device. Done.
