In one of my project i have a requirement where i need to migrate content from TeamSite to AEM, The source site is built using Team site CMS now it needs to be moved / migrate to AEM system.
Any pointers across this or any sample code snippet would really helpful or appreciable.
I am not sure what you mean by migration code. If you have content - such as HTML/images/videos in another CMS system, you need to build your AEM site using AEM templates and components, Then you need to organize your site into Header, body, nav and footer, etc. You can build the AEM site as shown here: Scott's Digital Community: Creating your First Adobe Experience Manager 6.3 website
Notice how the pages are organized, HTML is copied into components - like the footer component, etc.
In TeamSite content stored in the form of data capture record ( xml format).
In AEM content stored in the form of properties's value in JCR nodes.
Create a mapping between dcr (xml) nodes to jcr nodes/properties.
Then you can create a custom java application that can read xmls (dcrs) from TeamSite as an input and can create JCR node tree as per mapping and store content in the form of properties values in created jcr nodes in AEM.
