Re: Native and Mixed Mode Question sorry

Hi,

No, it's not the same. Switching AD to native will not switch Exchange to
native. You might even HAVE to switch AD to native first if you are, for
instance, going to use ADMT or another Migration tool (Quest AD Migrator) to
copy SID-history from an old domain to AD. AD Native mode will support also
Universal Groups and nesting of Domain Local Groups (from the same domain)
in Domain Local Groups and Domain Global Groups into Domain Global Groups
(from the same domain) . You might want to keep Exchange into mixed mode to
support Exchange 5.5, read this piece from the Exchange 2000 Admin training
guide:

-----
Exchange Mixed Mode
In mixed mode, administrative groups map directly to sites in an Exchange
Server 5.5 organization. This means that Exchange Server sites replicated to
Active Directory appear as administrative groups and administrative groups
replicated to the Exchange Server directory appear as sites. For backward
compatibility reasons, the mixed mode limits Exchange 2000 Server to
constraints imposed by earlier software releases.

The following limitations apply in mixed mode:

a.. Administrative groups are handled similar to Exchange Server 5.5
sites.
b.. It is impossible to move mailboxes between servers in different
administrative groups.
c.. Routing groups can only contain servers from the same administrative
group. Although one administrative group may contain multiple routing
groups, routing groups cannot span multiple administrative groups.
Exchange Native Mode
You can switch Exchange 2000 Server to native mode if you don't plan to use
previous versions of Exchange Server or as soon as you have upgraded all of
your servers. In native mode, earlier release restrictions, which limit the
flexibility of routing groups, don't apply. Hence, routing groups can
contain servers from multiple administrative groups, and you gain the
ability to create administrative groups independently of the routing
infrastructure for your organization. It is also possible to move servers
between administrative groups should the underlying infrastructure require
this kind of change.

NOTE
------------------------------------------------------------------------------
Keep in mind that switching to native mode is an irreversible process; you
cannot go back to mixed mode. It is likewise impossible to install earlier
versions of Exchange Server into a native mode organization.
-----

But before switching to any native mode, always create an extra AD
SystemState backup. If you find out you should not have switched to native,
you can perform an Authoritative System State restore and then you are back
in mixed mode...
