After Fully downgraded featureCompatibilityVersion:
Upgrading featureCompatibilityVersion:
Downgrading featureCompatibilityVersion:
Fully upgraded featureCompatibilityVersion:
We should document the change to the getParameter output. We should also include in the downgrade instructions to wait for each node to have fully downgraded featureCompatibilityVersion before replacing the binary. |

It is hard to see the targetVersion in the getParameter output, since usually we proceed immediately into the fully upgraded or fully downgraded state. One way you can be sure to see it is by doing a direct write to admin.system.version, as in this test. Of course, we don't want users to write directly to admin.system.version, but this will allow you to observe the targetVersion in the getParameter output. How you might see it in the real world is when the config primary can't connect to one of the shards during upgrade or downgrade, so it cannot complete the upgrade or downgrade process. We simulate that in this test. |
