I am currently running Magento 2.0 for my store. I have tried to upgrade to 2.0.2 but not successful. I have installed a clean 2.0.2 server with all extensions and theme like I had in my 2.0 store. What do I have to copy from 2.0 store to 2.0.2 store before switching the database in 2.0.2 store to point to 2.0 database? Can I use the 2.0 database directly in 2.0.2 store?
Did you follow instructions posted here? http://devdocs.magento.com/guides/v2.0/release-notes/tech_bull_201-upgrade.html
This tool allows you to upgrade from your Magento to any version of Magento directly with ease. I see a lot of positive reviews http://tinyurl.com/zeqk3ue
