I am working on a old small site built on CQ 5.5 In this older implementation they have copied the Out of the Box Blog components into the apps folder. It looks like they copied the out of the box Blog page component into the apps folder and customized it. This components uses the a lot of older API's. I have listed some of them below. Most of these are not present any more in AEM 6.2. As a sample i have also given the feed.jsp which is a part of blog page. The feed uses Atom feed renderer for blog and blog entry nodes.
There is also a lot of content they built using these blog templates. Can anyone please advice how can i upgrade these components and how i can migrate this content. Is there a one on one replacement for these API's? Also any ideas how i can migrate the blog content.
There is not a tool that will migrate fromCollabto SRP/SCF (1->3). AEM 6.2 no longer has the bundles for the bucketing/indexing services, so thecollabmigrate tool (which existed in 6.0 upgrade) will not start in AEM 6.2.
The most practical option IMO would be to customize the aem-communities-ugc-migration tool since source is posted on github at the above link
