About 3 months ago I defragged a 28GB IS (exch 5.5 sp3) down to about 22GB...it took about 12 hours (this was on faster hardware than the production machine -- I was doing testing in our test lab).
Why not build the new server on your SAN (different server name, part of the same site) and move the user mail bags to the new server? You'll have to leave the old server up for awhile (we do for about 2 weeks) so that the users email client will automatically update to the new server. > ---------- > From: Crosby, Tim (Sarcom)[SMTP:[EMAIL PROTECTED]] > Reply To: MS-Exchange Admin Issues > Sent: Friday, December 07, 2001 1:49 PM > To: MS-Exchange Admin Issues > Subject: RE: Defragging the IS > > OK, what would be a more realistic estimate then?
