I am being asked to update my WordPress version to 3.5
However, if I update am I going to lose my files and data on my website?
It displays this message:
Important: before updating, please back up your database and files. For help with updates, visit the Updating WordPress Codex page.
Is there a certain step I have to take before updating to 3.5 to ensure my website will still work and all the files will still be in place?
