I am automating this AEM upgrade from 6.0 - 6.3 using Chef cookbook/recipes. For this I need to write two recipes. One which will automatically backup the repository content and other will upgrade the packages to 6.3. Any suggestions?
Thanks for your suggestion marc. We would love to upgrade it directly to 6.5, but all this, automation and upgrade are client requirements which I personally cannot change. That was a nice piece of information though.
