My apologies for the length of this post.
I am in the process of preparing to upgrade WPMU from 1.2.1 to 1.2.5. Step 7 in the documentation explains that while you need to delete the old WP files before uploading the new ones, there are exceptions - such as wp-config.php, wp-content, etc - that need to be left in place. It then says to upload the new files. I just want to make sure that I do this correctly, so here's my question. Once I've deleted the all old files except for the few that they say to leave, do I then upload ALL the new files, or all of them except those files (wp-config.php, wp-content, etc) that I've left in place?
I appreciate your feedback.
