 3. Bump mongodb sharded version in charts => `CHART_MONGO_SHARDED_VERSION` in the `solution-base/mongodb/Makefile` file (e.g. `CHART_MONGO_SHARDED_VERSION:="6.6.7"`)

 7. After upgrading, you may need to apply additional changes that are not directly handled by the charts or patches. For example, when upgrading to MongoDB 6.0, you need to switch from using `mongo` to `mongosh`. Refer to the release notes for the new version (e.g., `https://www.mongodb.com/docs/v6.0/release-notes/6.0/`) for details on these additional changes.
 8. Passing CI tests is not enough, you must also perform an upgrade check with the product(s) using this Zenko version, before merging the upgrade PR. Some changes may be required at upper-levels (e.g., update mongosh commands, or add new logic in the upgrade).
