Migrate AEM user to another AEM instance

We create users in AEM DEV instance and need to move those users to higher environments. We can create a package using ACL packager.

Download the ACS AEM commons packages
Install the packages into AEM using the package manager
Navigate to AEM > Operations > Configuration
Expand Tools > Content Packagers and create a new page

AEM as a Cloud Service

For the last few years, Adobe Experience Manager (AEM) has been available as On-prem and Adobe Managed Services (AMS)

There are intrinsic differences between these previous approaches and AEM as a Cloud Service:

• Architecture
• Upgrades
• Cloud Manager
• Onboarding
• Developing
• Operations and Performance
• Identity Management
• Authoring User Interface
• AEM Sites
• AEM Assets

AEM as a Cloud Service Benefits

Version Less AEM: 

No need to worry about upgrading to the latest AEM version. When a new version is available, we can upgrade from the Cloud Manager CI/CD pipeline which is fully automated.

Quick Time to Market: 

AEM as a Cloud Service assists you in quickly delivering the products, services, and experiences faster without developing customized content management systems.

Auto-scalable: 

It can scale automatically based on traffic and operations. It requires less support and maintenance efforts.

Separation of code and content: 

Custom code and configurations are clubbed into the AEM base image which is then used to create multiple Author and Publish nodes. The changes to the code and configurations are made only through CI/CD pipelines in Cloud Manager.

 Security: Industry standard security measures will be taken care of.

Update Content using Launches in AEM

Launches in AEM enable you to efficiently develop content for a future release. A launch is created to allow you to make content changes for future publication (while maintaining current pages). After editing the launch page, you need to promote the Launch. So the edited launch page will be published on the live date.

For example, you have an online store and you need to display promotional info x-mas and New Year. To do this, you can create a launch page and set it to publish on 25th Dec. Create another launch page for New Year.

Creating a Launch:

Launch can be created from two consoles in AEM

1. From Navigation -> Sites -> Create button ->Launch 
2. From Tools -> Sites -> Launch

Navigate to Sites, create a Launch

Groovy Script Console integration in AEM

Introduction

Groovy was developed by Jochen Theodorou, Guillaume Laforge, Cedric Champeau, and Paul King. Its typing discipline is strong, static and dynamic. It was licensed under the Apache 2.0 license. It first appeared in the year 2003. Its file extension is .groovy and was designed by James Strachan.

License	It was licensed under Apache license 2.0	It was licensed under GNU General Public License.
Imports	All the packages will be imported by default.	It has to be mentioned clearly to import any package into the java class file.
Documentation	It provides single page documentation.	It has documentation in the form specification given by JCP.

Setup:

1. Download the Groovy Console package. Check the version compatible with your AEM instance. For AEM 6.5 I am using 14.0.0 version.
2. Install the downloaded package using the CRX package manager.
3. To verify the installation, open http://localhost:4502/apps/groovyconsole.html in browser to view the groovy console.

Note: From 13.0.0 release, paths were changed from /etc/ to /apps/ to access Groovy Console

GUI Console:

Create a system user in AEM using runmode config

Add/create a system user through runmode in AEM using ACS commons.

Create a runmode config file in your project.
/apps/aemquickstart/config/com.adobe.acs.commons.users.impl.EnsureServiceUser-customServiceUser.config

Add below snippet in the config file

principalName="custom-service-user" 
type="add" 
ensure-immediately="{Boolean}true"
aces="[type=allow;privileges=jcr:read\,jcr:modifyproperties;path=/content/we-retail;rep:glob=/jcr:content/*,type=allow;privileges=jcr:read;path=/content/aemquickstart;rep:glob=/jcr:content/*]

Above snippet will add read and modify properties privilege to /content/we-retail path and read permission to /content/aemquickstart.
