Re: Exchange 5.5 to Exchange 2003 standard upgrade process question.

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi,

You don't need to have the AD in native mode, but it is recommended.

Reason for this:
When migrating distribution lists these are converted to universal security
groups if they have been used as security principals (used to add
permissions on public folders or user folders in exchange 5.5) and therefore
all permissions on folders can be migrated directly.

If the domain is in mixed mode the distribution lists are converted to
universal distribution groups which can't be used for adding permissions and
you will therefore loose all added permissions to the above mentioned
folders.
