Hi, I've been thrown into the deep end at work. I have been asked to do something i don't know anything about. Currently we are running exchange 5.5 on win nt. But the boss wants to upgrade to E2K and W2K. Seeing that the server is mission critical i am very nervous about running upgrades on it. So I came up with a non-stressful idea, i just don't know if it would work. Is it plausible to do a clean install of W2K and E2K on a new harddrive (the databases are small) and copy over exchange 5.5 information stores? Any help in this area would be greatly appreciated. References, tips, anything. Thanks in advance.
