+
+## How to upgrade
+
+**Automatic upgrade**
+
+For an automatic upgrade, use the [JHipster upgrade sub-generator](/upgrading-an-application/) on an existing application:
+
+Upgrade your version of JHipster:
+
+```
+npm update -g generator-jhipster
+```
+
+And then run the upgrade sub-generator:
+
+```
+jhipster upgrade
+```
+
+You can also use the [migrate blueprint](https://github.com/jhipster/generator-jhipster-migrate) for more advanced upgrade features.
+
+```
+npm i -g generator-jhipster-migrate
+jhipster-migrate
+```
+
+**Manual upgrades**
+
+For a manual upgrade, first upgrade your version of JHipster with:
+
+```
+npm update -g generator-jhipster
+```
+
+If you have an existing project, it will still use the JHipster version with which it was generated.
+To upgrade your project, you must first delete its `node_modules` folder and then run:
+
+```
+jhipster
+```
+
+Since JHipster 8.0, this command will update your project and all its entities.
+
+You can also update your entities one-by-one by running again the entity sub-generator, for example if your entity is named _Foo_, use:
+
+```
+jhipster entity Foo --single-entity
+```
