Certain elements of a version 4.1 configuration are not
automatically migrated during an upgrade. The previous sections
mentioned features, such as multicast file transfer, that are not
migrated. In addition, migration does not remove content, such as
files, folders, and certain registry settings, even though the
content may be obsolete.
The following list describes elements that are not migrated and
the manual configuration that might be necessary:
Security accounts and groups. The NetShow®
Administrators or Windows Media Administrators local groups and the
NetShowServices local user accounts are not removed during the
upgrade process. To ensure maximum security, decide whether the
accounts are still applicable, and then make them unavailable or
remove them if they are no longer in use.
Access control lists (ACLs). ACLs that are associated
with publishing points are not migrated. However the information is
not removed from the system registry. If you want, you can remove
the ACL information manually from the registry, by removing the
following registry subkeys:
If you want to reassign ACLs, you must enable the WMS
Publishing Points ACL Authorization plug-in.
Authorization and authentication plug-ins. These
plug-ins are not removed during migration. You can manually remove
them after the upgrade is finished.
IP access lists. The list of IP addresses that you have
configured to grant or deny access to your server are not migrated.
You can recreate these lists by using the WMS IP Address
Authorization plug-in properties dialog box.
Programs. All programs are migrated to playlists
regardless of whether they contained streams, with the exception of
programs containing multicast file transfer streams. You can remove
the empty playlists if you choose.
Configuration folders. The following folders and any
files contained in them are not removed:
You can manually remove the folders if you
Distribution Authentication. If you enabled server
authentication proxy settings in Windows Media Services version
4.1, the name of the proxy server used to validate authentication
credentials will be migrated during the upgrade. However, you must
manually enter the user name and password used with the proxy
server in the property sheet of the WMS Network Data Source
plug-in. You must specify the user name and password for each
protocol that uses the proxy server to connect to a network data
source. For more information, see To configure the WMS
Network Data Source plug-in.
On-Line Broadcast. This service, which provides
integration with Microsoft PowerPoint, is not migrated. If you are
running programs that require this service, you must continue to
use Windows Media Services version 4.1 on a compatible operating
system, such as Windows 2000 Server.
Windows Media File Transfer Services. This service is
not migrated. If you are running programs that require this
service, you must continue to use Windows Media Services version
4.1 on a compatible operating system, such as Windows 2000
Third party plug-ins. Third-party plug-ins used with
Windows Media Services version 4.1 cannot be used with the new
version of Windows Media Services. Several software developers have
created new plug-ins for this version. Check with the plug-in
developers to find out whether new plug-ins are available.
Incompatible publishing points. If a publishing point or
station on your Windows Media Services version 4.1 server has a
name that exceeds 260 characters it will not be migrated.
Incorrectly editing the registry may severely
damage your system. Before making changes to the registry, you
should back up any valued data on the computer.
