Actually, I have followed the migration instructions in the link below and I have succeeded to migrate amd64/ubuntu16 cards without any troubles. But the problem occurs with rapsbian-9, the process (execution logs) seems to be fine, I have received “migration successful, please reboot system”. After the reboot, nothing changes, it booted to raspbian-9 and not from the modified initramfs.
Migration instructions: https://github.com/balena-io-playground/balena-migrate.
These are my steps run inside the RPI3 that i want to migrate :
1- git clone https://github.com/balena-io-playground/balena-migrate && cd balena-migrate/migratecfg
2- wget https://files.resin.io/resinos/raspberrypi3/2.43.0%2Brev1.dev/image/balena.img.zip # In order to download the balenaos rpi3 image
3- cp balena-migrate-sample.conf balena-migrate.conf # then updating the IMAGE_FILE environment variable and setting REQUIRE_NMGR_FILE=FALSE
I appreciate any hint or help.
