Publishing to a server with an existing webpage

I made a webpage for a client who already has a webpage online. I’ve already got the FTP address for their server from their IT team, so everything’s ready for publishing.

My main doubt here is, will it just work? will it just overwrite the old webpage? My other concern is, since they use that server for mail, will publishing it there mess up with that?

If you publish the site, your files will overwrite those already on the server. Any files that may have different names to the ones you are uploading will remain on the server, and will probably have to be deleted manually. Uploading a new website will have no effect on emails associated with the domain - these will continue to work as normal


Thank you so much for your answer! I’m new at this and I’m trying to be as cautious as possible.
