Is there a way to get all the Segmentation / Campaign available programmatically ? Basically any API available to handle the campaigns manually

6.1 docs updates are still happening. You can raise a support ticket for the same

For clustering from AEM 6.x versions, you need to use MongoMK. refer [1] for the recommended deployments[1] http://docs.adobe.com/docs/en/aem/6-1/deploy/recommended-deploys.html

check this [1] on the complete integration with Adobe Analytics[1] https://docs.adobe.com/docs/en/cq/5-6-1/administering/integrating_with_adobe_marketing_cloud/sitecatalyst.html

You need to map your localhost to a domain in your web serveralso check this to setup dispatcher https://docs.adobe.com/docs/en/dispatcher/disp-config.htmland https setup https://docs.adobe.com/docs/en/dispatcher/disp-ssl.html

When we use the mobile add on for the aem site, internally will it do the redirect or the forward the request once it identifies the device by default

yes it is possible. refer [1] and [2] for the same[1]https://docs.adobe.com/docs/en/aem/6-0/develop/ref/javadoc/com/day/cq/dam/commons/watermark/package-summary.html[2] http://adobe-consulting-services.github.io/acs-aem-commons/features/dam-workflow-processes.html

I dont see these packages in 6.1 here [1]. There are quite a few changes in the social component framework. You might have to change your code accordingly. If you find difficult, log a support ticket to get help on this.[1] http://docs.adobe.com/docs/en/aem/6-1/ref/javadoc/overview-summary.html

I dont see there is any configuration option given for this. You might have to export that jar and change the scheduler time

basically, Your organization's Adobe Marketing Cloud administrator must grant you web services access privileges before you can use the Enterprise API.
