Sorry about that, wouldn't you know I clicked the wrong button.

Anyway...
I would agree, but ONLY IF I knew absolutely without doubt that there wouldn't be any problems with the delivery. Unfortunately, I have never had a perfect delivery when it comes to software upgrades. If there really are Win3x, 9x and NT systems still in use, I wouldn't expect that data compatibility would be an issue, at least internal to the company. I've done both and gradual replacement saves on medical costs (Aspirin, Tylenol and "Sick Days"). I'm also a little biased as I am a member of a "Help Desk of 2" for 450 users.
