+## Upgrade from v7
+
+The default ZITADEL version is now >= v2.55.
+[This requires Cockroach DB to be at >= v23.2](https://zitadel.com/docs/support/advisory/a10009)
+If you are using an older version of Cockroach DB, please upgrade it before upgrading ZITADEL.
+
+Note that in order to upgrade cockroach, you should not jump minor versions.
+For example:
+
+```bash
+# install Cockroach DB v23.1.14
+helm upgrade db cockroachdb/cockroachdb --version 11.2.4 --reuse-values
+# install Cockroach DB v23.2.5
+helm upgrade db cockroachdb/cockroachdb --version 12.0.5 --reuse-values
+# install Cockroach DB v24.1.1
+helm upgrade db cockroachdb/cockroachdb --version 13.0.1 --reuse-values
+# install ZITADEL v2.55.0
+helm upgrade my-zitadel zitadel/zitadel --version 8.0.0 --reuse-values
+```
+
+Please refer to the docs by Cockroach Labs. The ZITADEL tests run against the [official CockroachDB chart](https://artifacthub.io/packages/helm/cockroachdb/cockroachdb).
