I decided to retire one of the servers, an old original series one Apple XServe, I say old it’s about 5 years. However the retirement plan worked out to be more messy than I had hoped. Everything including a multitude of sites were re-located on a new server at a different venue, all was well until I discovered that everything on the new system required case sensitivity, whereas on the Unix based Mac it did not, that is to say the database calls and referenced files, which had been uploaded by clients might have been mypicture.JPG whereas it should have been mypicture.jpg. No much difference but it has caused a real problem changing file and database references but not other syntax, across literally thousands of files.
