As the title stated, how do I upgrade SaltStack (both Master and Minion) if I installed them using the bootstrap.sh script?

By default the bootstrap.sh scripts installs the stable version of SaltStack. Depending on your OS you can upgrade SaltStack using you package manager.

For example on you salt-master (OS: Ubuntu) you might run the following commands:

sudo apt-get update
sudo apt-get upgrade salt-master

On your salt-master you can get a list of what version of SaltStack your minsions are running:

sudo salt '*' test.version

To get a list of up-to-date minions and those that need updating, you can run the following command on your salt-master:

sudo salt-run manage.versions

You can use SaltStack to upgrade all of your salt-minions at once:

sudo salt '*' pkg.install salt-minion refresh=True

An alternative method would be to use the apt commands like this:

sudo salt -G 'os:Ubuntu' cmd.run "apt-get -y install salt-minion"

Verify that everything is upgraded by running sudo salt '*' test.version again.
