What is Multi Site Manager (MSM)
Multi Site Manager (MSM) allows aem developers to create copy of existing site and automatically update the copy when changes are done to the source site.

Advantages of using MSM :
Easily manage multiple websites that share common content.
MSM allows aem developers to define relations between the sites so that content changes in one site are automatically replicated in all other sites.
Reduces the time to manage your websites and increases the re-use of common content.
Maintain common look and feel across all websites.

When we should use MSM
  • Sites are in multiple countries.
  • Sites are in multiple languages.
  • Need to reuse/replicate same content in multiple websites.
  • Maintain consistent branding and content across websites.
Manage different language versions using MSM
The biggest advantage of using MSM over internationalization is ease to add new languages to websites. To leverage MSM functionality a website must follow below structure:-
  • The web site should have a single page as the root.
  • Each child page is the root page of each language version.
  • The name of the child page is the language code.
Lets see how to add a new language support to existing website using Multi Site Manager (MSM).
Steps to add a language to website using MSM
  • Open SiteAdmin console, select the root page of website.

  • Click New > New Page.

  • In create page dialog , enter Title and the Name. Remember Name should be in <language-code> or <language-code>_<country-code> format. You can see the list of default languages-code that comes with AEM at /libs/wcm/core/resources/languages node.

  • Select your template and click Create.

  • From Website(SiteAdmin) Console, select the root page of website.
  • Go to Tools menu –> Select Language copy.

  • After clicking language copy option, it will open a table which consist of all languages in which this website is currently supported. An X mark against any page means that it is available in this particular language.
  • To copy a page in new language, simply select the cell and choose one option from drop down menu. Below we are copying company page to Russian language.


  • Select Language copy Type and click OK.
  • Confirmation dialog will Pop up. Click Yes to copy.
Create a Blueprint in MSM
Blueprint allow us to control multiple live copies and apply consistent rollout configurations to all blueprint’s live copies. Using blueprint rollout feature we can push modifications to all it’s live copies simultaneously.

Follow the below steps for creating a blueprint in AEM.
  • Go to Tools console.
  • Under Tools –> Select MSM Control Centre (Root Folder).
  • Click New –> New Page in top Right Corner.

Create Page dialog will Open. Enter below details :
Title – Enter page title.
Name – Enter name in lower-case without space as this will be out Page node in crxde.

You can also see a link (show in control centre) in bottom for Blueprint Control Centre.


Note: Managing huge number of sites is always tedious even if they are live copy. Blueprint Control Centre saves us from this tasks by centrally managing all the live copies under one blueprint Page in an organized way.
