Prerequisites

• I have updated the public deprecation schedule
• I have written a descriptive issue title

Description

Helm V2 had been flagged for deprecation since 2024.1 with the functionality deprecated since 2024.3. We are now removing Helm V2 code from the product.

This follows issues #8627 and #8835

Process

• The functionality will be marked as deprecated in code, causing any usages to be logged for monitoring purposes
• After the notification period of at least 6 months the functionality will be toggled off, resulting in an error when attempting to use it. Customers can toggle this back on if they still require it.
• After another 12 months the functionality will be completely removed

Migration Guide

There is an official Helm V2 to V3 Migration guide that details the steps to follow. Once this has been performed, customers will need to update their Helm Upgrade deployment step to change to Helm V3.
