Using GPO to deploy Office 2007 over manually installed Office 2002
I have a base of 25 XP Pro machines in an AD domain with Office XP and Publisher 2002 installed manually at some prior point. I now want to update them to Office 2007 SB which includes Publisher. I would like to install this using GPO. Mostly for practice. The servers are 2003 R2 .
I know I have to remove the existing Office installation manually before I do this, but I am wondering if it's really worth the trouble. I mean sure next time Office gets updated it would be worth it as the update can occur using the GPO but I have only deployed one item using GPO and it was designed specifically for that purpose so it worked perfectly.
Will Office 2007 be as kind? I want to do this but I want to be practical too. I welcome advise and counsel.
