# Upgrade guidelines

## To 0.20

The `observability.<sub chart>.enabled` parameters have been moved to an
`enabled` parameter within the sub chart itself. If you had changes to these
parameters, you will need to update your changes to work with the new structure.

## To 0.18

The `serviceType` and `servicePort` parameters have been moved under a `service`
parameter with names of `type` and `port` respectively. If you had changes to
these parameters for any demo component, you will need to update your changes
to work with the new structure for the `service` parameter.

## To 0.13

Jaeger was moved to a Helm sub-chart instead of a local chart deployment. If you
had changes specified to the `observability.jaeger` parameter, those changes
will need to be re-implemented as sub-chart parameters under the top level
`jaeger` parameter instead.
