I have Xenforo 1.5.2 and have never upgraded before, so am unsure what to do so as to avoid screwing stuff up. So just have a couple of questions that aren't cleanly answered in the help file.
I have a Macbook Pro and use FireFTP as my FTP client. The database has also been fully backed up (using Navicat MySQL). And I have downloaded the latest upgrade package.
My primary question relates to uploading the files.
In the "Upload" folder there are four additional folders, along with a dozen or so individual files. To take for example the "Styles" folder - do I simply use FireFTP and copy it over in its entirety? When I attempted to do that, I was given the option in FireFTP to "overwrite" or "Overwrite All." If I select "overwrite all," will only the new, changed files in the Styles directory be overwritten - while files that aren't changed in the upgrade be maintained as they are on the server? Or will the "overwrite"/"overwrite all" essentially nuke everything inside the current styles directory on my server and replace it with the new styles folder?
