+#### Auto upgrade
+With this parameter you can influence the behaviour during an operator upgrade.  
+If set to `true`, the operator will upgrade the specific instance directly.  
+When the value is set to `false`, and we have a running deployment, the operator will not update the AWX instance.  
+This can be useful when you have multiple AWX instances which you want to upgrade step by step instead of all at once.

+| -------------| ---------------------------------- | ------- |
+| auto_upgrade | Automatic upgrade of AWX instances | true    |
+
+Example configuration of `auto_upgrade` parameter
+
+```yaml
+  spec:
+    auto_upgrade: true
+```
+
+##### Upgrade of instances without auto upgrade
+
+There are two ways to upgrade instances which are marked with the 'auto_upgrade: false' flag.  
+
+Changing flags:
+
+- change the auto_upgrade flag on your AWX object to true  
+- wait until the upgrade process of that instance is finished
+- change the auto_upgrade flag on your AWX object back to false  
+
+Delete the deployment:
+
+- delete the deployment object of your AWX instance  
+```
+$ kubectl -n awx delete deployment <yourInstanceName> 
+```
+- wait until the instance gets redeployed
