Roaming profiles & different app versions

[mrsh]

We're in the midst of a desktop rebuild project and will shortly migrate 1500+ machines from XPSP2/Office2003/IE6 to XPSP3/Office2007/IE8. We want to integrate the new environment within the existing O.U./GPO structure within A.D. to allow users to 'roam' between both the old and new environments. For starters, we can add the IE8 & Office 2007 ADM files to the existing GPOs with Office 2003 ADM files, however...

1. Do you recommend this approach? Is there a Microsoft Best Practice guide for this scenario?
2. I have read User Data and Settings Management which advises to "Make sure that you have the same application versions installed." Do we need to be concerned about any potential application conflicts due to the different versions of applications, such as Office 2003 and Office 2007?

Any advice would be much appreciated.

Thanks
Scott

I would try to:

() Use a Win7 management station to create all my GPOs
() Create the central store
() Use the Office 2007 ADMX files
() Utilize Office 2003 ADM files only when necessary within specific GPOs

and.. that's it.

Other than that, you should be on the right track.
