It doesn't touch the structure of the data pages as a prerequisite of the upgrade completing. The pages are updated and touched "lazily" meaning they're updated as they're touched by the users or by maintenance (online or offline) activities. So the upgrade will complete, then as the database is used over the next several hours, days, weeks, months, it will get updated.
Exchange 2003 is more involved than a service pack, but it's been better tested. I don't like doing the first of a new version as an in place upgrade, but I don't have a problem doing in place upgrades per-se. I'll often install a temporary system with the new version, then do the in place upgrade, then remove the temporary system. I'm also a real stickler for extra backups. It doesn't hurt to also run isinteg and/or eseutil after the backups to ensure there are no lingering structural issues in the database. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of MS Exchange List Posted At: Wednesday, May 12, 2004 7:02 PM Posted To: Microsoft Exchange Conversation: in-place upgrade exchange2000 to exchange2003 Subject: RE: in-place upgrade exchange2000 to exchange2003 So, it's mainly a Code update that doesn't touch the structure or tables of the database? We do Service packs, etc... without moving all the users to another server, I'd actually consider an Inplace upgrade if we're just talking about code.

I always do two - one online backup and one offline backup. The install itself is not size driven though. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Webb, Andy Posted At: Wednesday, May 12, 2004 6:53 PM Posted To: Microsoft Exchange Conversation: in-place upgrade exchange2000 to exchange2003 Subject: RE: in-place upgrade exchange2000 to exchange2003 It's not dependent on the database size. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David, Andy Posted At: Wednesday, May 12, 2004 11:20 AM Posted To: Microsoft Exchange Conversation: in-place upgrade exchange2000 to exchange2003 Subject: RE: in-place upgrade exchange2000 to exchange2003 Wouldn't know as I would never do an in-place upgrade myself. -----Original Message----- From: Microsoft Exchange List Server [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 12, 2004 11:57 AM To: Exchange Discussions Subject: in-place upgrade exchange2000 to exchange2003 Hi all Please Do you know how long does it take an in-place upgrade exchange2000 to exchange2003.
