Database Decomposition to Main and CI: Migration documentation missing for helm chart
Problem to solve
What product or feature(s) affected?
The Database Decomposition to Main and CI feature is affected, which is mandatory with Gitlab 17.x. We didn't find any migration documentation for helm deployments.
What docs or doc section affected?
We found a documentation for Linux Package Installations, but not especially for Helm Deployments.
Link to documentation: https://docs.gitlab.com/ee/administration/postgresql/multiple_databases.html
Proposal
We would like to have detailed step-by-step instructions on how to migrate from a single database (we use an external database) to the decomposed setup when using a helm chart deployment.
