For future reference, you can review the changelog for the intervening versions including current and planned upgrade version. I found zero breaking change announcements between your current version 0.34.1, which was incidentally the final release before 1.0.0, and 1.1.9 which is the ziti version used by the latest chart.
The next question is "What significant changes have occurred for Helm charts since the chart that provided ziti controller 0.34.1?"
This is more complex, but here are some highlights from the diff:
- the console chart is deprecated by a built-in console in the controller deployment - the console URL is printed after
helm upgrade - the controller chart has an optional "Prometheus Operated" ServiceMonitor resource available
- ziti networks require a trust domain: set
.Values.trustDomainor a random value will be generated and stored in a secret
