I need to upgrade Firmware on two Cisco switches SG300-10 to the latest version 1.4.8.06. Those switches have currently installed version 1.0.0.27. So, there are 15 Firmware releases in between those two. Can someone please suggest what would be the correct process to accomplish this upgrade?

Cisco Tech Support suggested the below solution.
To have Firmware upgraded from the oldest version (1.0.0.27) to the latest version (1.4.8.06), you need to install several times interim Firmware versions and upgrade once the Boot Code. Every time the interim Firmware loaded, the Network Switch should be rebooted to that version. Follow the bellow installation order:
1. Firmware version: 1.2.7.76 sx300_fw-12776.ros
2. Firmware version: 1.3.0.59 sx300_fw-13059.ros
3. Firmware version: 1.3.5.58 Sx300_FW_Boot_1.3.5.58.zip
sx300_fw-13558.ros - Firmware
sx300_boot-13506.rfb - Boot Code
4. Firmware version: 1.4.0.88 Sx300_FW_Boot_1.4.0.88.zip
sx300_fw-14088.ros - Firmware
5. Firmware version: 1.4.1.03 Sx300_FW_Boot_1.4.1.03.zip
sx300_fw-1413.ros - Firmware
6. Firmware version: 1.4.8.06 sx300_fw-1486.ros
