+### Updating Tenant Databases for Link Feature
+To support the Link feature, additional database columns are introduced.
+Upon re-deployment of your multitenant application, you may encounter "invalid column" errors if tenant database containers are not updated.
+
+To resolve this, ensure the following hook command is added to the mta.yaml for the sidecar application.
+```
+hooks:
+- name: upgrade-all
+type: task
+phases:
+- blue-green.application.before-start.idle
+- deploy.application.before-start
+parameters:
+name: upgrade
+memory: 512M
+disk-quota: 768M
+command: npx -p @sap/cds-mtx cds-mtx upgrade "*"
+```
+This will automatically update tenant databases during deployment. See this [example](https://github.com/vibhutikumar07/cloud-cap-samples-java/blob/31009de404af0ddc92b8c593b21395757ed053e6/mta.yaml#L71).

 ## Support for edit of link type attachments
 
 This plugin provides the capability to update/edit the URL of attachments of link type.
