@sagrawal Could you please elaborate your requirement ? It will depend on what you want to do? Are you planning to migrate an existing website to an AEM website ? Or is this something else. I was involved in a migration in which the website content was provided to us in XML formats in more than 300 zip files. And migrating that to AEM , is not easy task or something which is OOTB , you have to design the migration script according to the existing content and the components you have developed in AEM . A simple answer would be really difficult for this question.
