This is done automatically by Kubernetes when ConfigMap versions change. + +**Q: Is the migration reversible?** +A: No, the v1.1 format is replaced with v1.2 format. If you need to downgrade to v1.1.0, delete the ConfigMaps and the v1.1 operator will recreate them in the old format. + +**Q: What if I have customized the kbs-config.toml?** +A: TrusteeConfig-managed ConfigMaps are operator-generated from templates. If you need custom configuration, you should modify the TrusteeConfig CR or templates, not the ConfigMap directly. Direct ConfigMap edits will be overwritten during reconciliation. + +**Q: Can I disable automatic migration?** +A: No, but the migration is designed to be safe and non-disruptive. If you want manual control, upgrade to v1.2.0 with ConfigMaps already in the new format. + +**Q: How long does migration take?** +A: Migration is instant (< 1 second). The pod restart takes 10-30 seconds depending on cluster load. + +## Support + +If you encounter issues: + +1.
