Upgrading 1.x.x.x to 2.x.x.x
A helm upgrade is not supported from OneDB 1.0.0.0 helm chart to a OneDB 2.x helm chart. There are major differences between these two helm chart versions that would prevent a helm upgrade.
When upgrading from a helm chart version using OneDB 1.x to 2.x then you must perform a data migration. It is recommended to use the dbexport.
