I am working in a Magento store that was developed 2 years ago by other developers. I updated the Magento version, patches, etc. I also "cleaned" old files and folders but we still have unused files in the FTP, old themes folders and even extensions that we don't need anymore (I just deactivated it).
Now the company decided to do a complete redesign of the website. So, what is my best option?
Should I just start a new Magento installation to "clean" everything and import the customer/products/sales data? I feel that doing this I would have more "control" over the store. At the same time, I am afraid that we will lost data, since Magento DB is very complex.
Should I just "clean" whatever I can and install a new theme over the same website?
I appreciate any ideas or experiences that you guys had with that. Thanks!
