Are you interested in migrating to AEM as a Cloud Service? But, are unsure about how much time it will take or what changes you will have to do to your code to be compliant and have a working application.
In this blog, I’ll try to go over things that you should check your code for and also tools that are available to you for automating some of the changes needed to be compliant.
My recommendation would be to run the Cloud Readiness Analyzer before doing anything else and then follow this blog for further assessment. The CRA is available for download on the Adobe Software Distribution Portal
