# Modify Site

Attributes of an existing site can be modified using the `modify_site` workflow.
As a result, other subscriptions that rely on this site will have referenced 
attributes updated as well. 

!!! warning

    Be aware that although this *does* update attributes in the services 
    database, it does **not** update any active subscription instances that are
    already deployed. You will need to run additional workflows to update
    subscriptions that depend on this change
