1. First, edit upgrade-files/ to select what to be upgraded.

2. Then, run make-package.sh to generate upgrade package.

$ ./make-package.sh Generated package: whatsminer-$MACHINE_TYPE-$VERSION_NUMBER-upgrade.zip

The generated package contains three files:

- remote-upgrade.sh
- upgrade-$MACHINE_TYPE-$VERSION_NUMBER.tgz
- HOWTO

2. Prepare Miners IP list file ip.txt to be upgraded (one IP per line):

   $ cat ip.txt 192.168.1.10 192.168.1.11 ..

3. Run remote-upgrade.sh to upgrade miners.

$ ./remote-upgrade.sh upgrade-$MACHINE_TYPE-$VERSION_NUMBER.tgz ip.txt

Enjoy it.
