Dear community I currently upgrade my magento store manually, by replacing my files with the newer versions files manually using FTP (coda).
Has got me through many upgrades but is rather long winded. Thus, I was wondering if anyone could recommend a more suitable way to upgrade a magento store.
I know the different ways. i.e, connect manager but that is not a suitable way.
Looking at magento download site for the latest version (220.127.116.11) I see the ability to download a .diff file, which I believe checks differences from my version and new version and applies the changes.
I was hoping someone could kindly elaborate further on this, like what is different between the .diff and .sh files of each of the relative patches. i.e, SUPEE-10415?
