Yes, I've done this and it worked OK. I've never had the guts to do it on a production system 'though! I do feel that the "approved", safe method would be to do an archive, swap links, then a restore. However, this will of course only work if the ROOTPATH points to a link to the cooked file system, rather than just the name of the filesystem file. Neil Truby Chase Manhattan Bank Bournemouth, UK
