                change the deployment scripts.
Note: During the deployment of the update
                packages, the system will issue warnings and errors in deployment summary. It is
                safe to disregard this information
 
        At your development machine:
        - 
                 Download and install Sitecore Commerce Connect
                    from Sitecore Developers Network.
            
 
- 
                Download Sitecore Commerce Server Connect 7.5, MVCSite 7.5, and Sitecore
                    Merchandising Manager 7.5 update packages..
            
 
- 
                Download Deploy.zip.
            
 
- 
                Extract Deploy.zip to a temporary location.
            
 
- 
                Ensure your site variables are correct. Open and edit the
                        deployment\environment.xml file and edit the following
                    sections:
                
                    <Configuration identity="Domain.Dev.Existing">
<Configuration identity="Domain.Dev.Merge">
                 
                
                    - 
                        Ensure that the instanceName variable is set as your
                            Sitecore instance name,  and the installDir variable
                            is correct. In the following example, the installDir
                            variable is pointing to
                            c:\inetpub\SitecoreInstance
                        
                            <Variables>
<Variable identity="instanceName" value="SitecoreInstance" description="" />
<Variable identity="installDir" value="$(Join-Path -Path $INETPUB_DIRECTORY -ChildPath $instanceName)" description="" />
</Variables>
                            In the following example the installDir variable is changed
                                    to c:\inetpub\wwwroot.
                            <Variable identity="installDir" value="$(Join-Path -Path $INETPUB_DIRECTORY\wwwroot -ChildPath $instanceName)" description="" />
                         
                     
                    - 
                        Ensure that the SitecorePort variable is set
                            correctly.  Use IIS Manager to determine your site settings.
                        
                            <Variable identity="SitecorePort" value="7655" description="" />
                         
                     
                    - 
                        Ensure that the scHostHeaderName variable is set
                            correctly. Use IIS Manager to determine your site settings.
                        
                            <Variable identity="scHostHeaderName" value="SitecoreHost" description="" />
                         
                     
                    - 
                        Ensure that the MONGO_EXE_PATH variable is set correctly. This variable
                            indicates the root path of the Mongo DB installation. The script,
                            Deploy-Mongo-Clean.ps1 uses this variable to locate the Mongo DB
                            executable to use for dropping the analytics databases.
                        
                            <Variable identity="MONGO_EXE_PATH" value="C:\MongoDB" description="MongoDB Installation path" />
