Why XM0?

The Installation Assistant for XM Scaled setup package ships an XM1 topology - it installs a Content Management and a Content Delivery site as two separate roles. For local development that is usually more than you need. XM0 is the same thing collapsed into a single Standalone instance: one site that does both CM and CD.

There is no official XM0 package, but you can get there by trimming a few things from the XM1 setup before you run it, and by switching the role to Standalone afterwards.

Below are the changes I make, split into what to do before and after running the installer. Everything here was tested on Sitecore 10.4.1.

Before the installation

1. Download the graphical installer

Grab the Installation Assistant for XM Scaled, in my case it is Sitecore 10.4.1 rev. 012149 (Setup XM1 Developer Workstation rev. 1.6.1-r7), and unzip it.

2. Remove “cm” from the site prefix

Open setup.exe.config. The XM1 template defines two sitenames, one for CM and one for CD:

<parameter name="SitecoreContentManagementSitename" value="{Prefix}cm.dev.local" />
<parameter name="SitecoreContentDeliverySitename" value="{Prefix}cd.dev.local" />

Because we want a single standalone site, drop the cm suffix so the content management site gets the clean hostname:

<parameter name="SitecoreContentManagementSitename" value="{Prefix}.dev.local" />
<parameter name="SitecoreContentDeliverySitename" value="{Prefix}cd.dev.local" />

3. Remove the SitecoreCD registration

In XM1-SingleDeveloper.json, the modules are registered in the Includes section, right before the Register section:

"Includes" : {
    "IdentityServerCertificates":{
        "Source": ".\\createcert.json"
    },
    "IdentityServer": {
        "Source": ".\\identityServer.json"
    },
    "SitecoreSolr": {
        "Source": ".\\Sitecore-solr.json"
    },
    "SitecoreCM": {
        "Source": ".\\Sitecore-XM1-cm.json"
    },
    "SitecoreCD": {
        "Source": ".\\Sitecore-XM1-cd.json"
    }
},
"Register": {
    "Tasks": {
        "SetVariable": "Set-Variable"
    }
},

XM0 has no separate delivery role, so remove the whole SitecoreCD block from Includes:

"Includes" : {
    "IdentityServerCertificates":{
        "Source": ".\\createcert.json"
    },
    "IdentityServer": {
        "Source": ".\\identityServer.json"
    },
    "SitecoreSolr": {
        "Source": ".\\Sitecore-solr.json"
    },
    "SitecoreCM": {
        "Source": ".\\Sitecore-XM1-cm.json"
    }
},
"Register": {
    "Tasks": {
        "SetVariable": "Set-Variable"
    }
},

Now you can run the setup.

After the installation

1. Set the role to Standalone

The XM1 install leaves the site configured as ContentManagement. Open the site’s Web.config and change the role to Standalone so the single instance serves both CM and CD:

<add key="role:define" value="Standalone" />

That’s it - you now have a single standalone XM0 instance instead of the XM1 topology.

Happy Sitecoring!
