### AI overview

This tutorial discusses migrating embedded firmware from the ESP-IDF bootloader to MCUboot using ESP Self-Reflasher. It explains why bootloader compatibility matters during RTOS or platform migration and notes that direct serial flashing may be impractical for inaccessible devices.

### Source excerpt

Migration is a word that carries a weighty importance in many contexts. It means relocation, resettling or, in case of the tech area, it could mean upgrade or replacement. A variety of reasons may motivate the big decision of migrating an entire piece of hardware or software from a production running system.
