Migrating from Helm v2 to Helm v3

Users that are currently deploying the GitLab chart with Helm v2 should not use the Helm 2to3 plugin at this time. Issue #1982 has been raised that may leave the deployed chart in a state that does not allow Helm v3 to upgrade the deployment after using the 2to3 plugin.

While this issue is being investigated the GitLab chart should continue to be upgraded with Helm v2 until a fix is found. Please track the issue for more information concerning the investigation and when a fix becomes available.
