Cisco TELEPRESENCE MANAGEMENT SUITE EXTENSION - FOR MICROSOFT EXCHANGE 2.2 Administrator's Manual page 26

Note: Cisco recommends against using the option to "remove all users, groups, and settings" during
uninstall when performing an upgrade. If choosing to use this option, Cisco recommends waiting 24
hours before attempting to perform the Cisco TMSXE installation. This will allow the mailbox and
Active Directory changes to fully propagate.
When the uninstall is complete, you may be prompted to restart the server. If necessary, restart the
server.
To reuse the existing resource accounts, the accounts' mailboxes must be moved to a database on
the new target Exchange 2007 Server.

Use the Exchange Management Console or shell to move the mailboxes. See
article for assistance on moving mailboxes for Exchange 2007
Example: Using Exchange Management Shell to move a single mailbox.
Move-Mailbox contoso\john -TargetDatabase TargetDatabase "First Storage
Group\Mailbox Database" -SourceMailboxCleanupOptions DeleteSourceMailbox
 Next the mailboxes must be converted to the Exchange 2007 version of a Resource mailbox.
Example using the Exchange Management Shell:
set-Mailbox -Identity:ResourceName -Type:Room

Be sure the Active Directory user accounts for the resource accounts are in the same domain as
the Exchange Server where Cisco TMSXE will be installed.
 For security purposes, you may disable the Active Directory login for each resource account if
desired. Using the AD Users and Computers snap-in, set each resource account to Disabled.
You can now follow the standard Cisco TMSXE installation instructions with the following exceptions:

The existing Exchange Service user will automatically be detected and re-used. The
administrator will be given the standard choices to reset the password or supply a new one. For
the Cisco TMS-side service account, when prompted, use the Let the installer create a service
account if needed option. This will cause the service user on the Cisco TMS server to be reused,
and have its password and Service flag in Cisco TMS reset as part of the installation.

In the Configure Service Account on the Cisco TMS Server step, be sure to select Let the
installer create a service user if needed. The installer will detect the previously used tmsconfuser
account on the Cisco TMS server and re-initialize it for the new installation.
 After installing Cisco TMSXE, the first time the Configuration Tool is opened, the tool will detect
problems with the existing resource accounts. This is normal as the sinks were disabled when the
previous product was uninstalled. The configuration tool can automatically update the accounts
as needed; simply select Yes when prompted to correct the accounts.
The remainder of the upgrade to Cisco TMSXE is completed by following the normal Cisco TMSXE
installation steps. Your previously configured resource accounts will carry over to the new installation
automatically.
Note the following details regarding the installer and initial configuration:

Your previously configured resources accounts will appear in the right column as integrated with
Exchange automatically and require no further configuration.
 The Cisco TMSXE product no longer creates an Address List for integrated systems like the
previous product. This address list was always optional and could be removed post-installation.
Exchange 2007 by default has an 'All Rooms' address list and additional lists can also be created
by the administrator.
 If the TANDBERG supplied custom form was used previously, it should be updated with the most
recent form. Be sure to complete the Publishing the TANDBERG Form section of the installation
instructions to ensure your users have the most recent version of the form.

When using Asynchronous Booking (recommended), calendar permissions are no longer
required to book a system, so the security groups used by the previous product are no longer
required. Access to booking rooms is controlled by the settings defined on the resource's mailbox
and calendar. The existing security groups can be removed, or may be re-used if you wish to
allow users to be able to open the calendars of resources automatically. Be sure to set the
groups on the Resource Defaults tab in the Configuration Utility if you plan on reusing the groups.
