I am working with a company who currently runs a Microsoft AD 2003 environment. Currently they have roughly 200 users that are hosted on an off-site POP3/SMTP email server. I have got the owners to bite on switching to Exchange server. Since I haven't really don't a migration with exchange before of this size, I need a little planning help.
What I am trying to figure out is what is the best way to move all the PST files which are stored on all the client desktop/laptop PCs onto the user's newly created exchange box. Also, what is the best way to migrate the system. It appears this would have to be a process that is done overtime vs. a overnight thing since out of the 200 users 150 are laptops which roam throughout and aren't always in the office.
