Setting up a multi-stage staging environment

Issue

Is it possible to set up a staging configuration like DEV → UAT → PROD?
What settings are required to use multi-stage staging?

Environment

DXP 7.0, DXP 7.1, DXP 7.2, DXP 7.3

solution

The following properties can be used by setting them to true

    #
    # By default, in a remote staging environment, the live group is marked and
    # staging is prevented on the live group.
    #
    # To achieve a Content Development - UAT - Production environment, staging
    # must be enabled for the UAT live group involved. When staging is enabled
    # for this group, it becomes the live group with respect to the Content
    # Development server and a staging group with respect to the Production
    # server.
    #
    # Set this property to true to allow staging for a live group. If set to
    # true, staging can be turned on for a live group, so that it can
    # simultaneously act as both a live group and a staging group.
    #
    staging.live.group.remote.staging.enabled=false

When remote staging is set up normally, "Staging" cannot be selected on the site set as the publication destination
When this property is enabled, "Staging" can also be selected for the staging destination site.
In that case, the following message will appear during staging setup

Before you do this, please make sure your site is running clean and content is in sync between sites to avoid any issues!
