             Summary: Add explicit upgrade instructions to the docs
                 Key: MESOS-4859
                 URL: https://issues.apache.org/jira/browse/MESOS-4859
             Project: Mesos
          Issue Type: Improvement
          Components: documentation
            Reporter: Greg Mann


The documentation currently contains per-version upgrade guidelines, which for recent releases only outlines the upgrade concerns for that version, without detailing explicit upgrade instructions.

We should add explicit upgrade instructions to the top of the upgrades documentation, which can be supplemented by the per-version concerns.

This is done within the upgrade docs for some early versions, with text like:

{code}
In order to upgrade a running cluster:

Install the new master binaries and restart the masters.
Upgrade the schedulers by linking the latest native library and mesos jar (if necessary).
Restart the schedulers.
Install the new slave binaries and restart the slaves.
Upgrade the executors by linking the latest native library and mesos jar (if necessary).
{code}

Instructions to this effect should be featured prominently in the doc.
