+## Upgrades
+The Artifactory and Xray roles support software updates. To use a role to perform a software update only, use the _artifactory_upgrade_only_ or _xray_upgrade_only_ variable and specify the version. See the following example.
+
+```
+- hosts: artifactory
+  vars:
+    artifactory_version: "{{ lookup('env', 'artifactory_version_upgrade') }}"
+    artifactory_upgrade_only: true
+  roles:
+    - artifactory
+
+- hosts: xray
+  vars:
+    xray_version: "{{ lookup('env', 'xray_version_upgrade') }}"
+    xray_upgrade_only: true
+  roles:
+    - xray
+```
