Upgrade Instructions

Please review the MailMarshal User Guide before upgrading.

Trustwave MailMarshal 10.0 supports a direct upgrade from MailMarshal/Trustwave SEG 8.2.3 and above, including the public release of SEG 10.0.0. (Upgrade from SEG 10 Beta releases is not supported).

If your installed version does not support direct upgrade, you can upgrade in steps.

Upgrade Preview

A standalone tool is available to check prerequisites and potential configuration issues before upgrade. See the product download page.

Database Prerequisites

SQL 2014 is the minimum SQL Server version supported.

Upgrading a Single Server

To upgrade a single MailMarshal server from any version supporting direct upgrade, install the new version on the existing server. You do not need to uninstall your existing version. The database will be upgraded in place, if necessary.

Upgrading an Array of Servers

You must upgrade each server by logging on locally. The remote upgrade feature that was present in earlier versions will not be available in MailMarshal 10.X.

Upgrading a Database

In the MailMarshal Server Tool, if you select a database that can be upgraded (version 8.2.3 or later 8.2.X), you will be given the option to upgrade and use the database.

Importing an 8.2 Configuration Backup

After installing MailMarshal 10.X, you can import a configuration backup from version 8.2.3 or later 8.2 version.

Convert the backup to the 10.X backup format (zip file) using the MMConvConfig command line tool found in the MailMarshal 10.X installation folder.
Import the converted configuration zip file using the Restore function in the Management Interface, or the MMExportConfig command line tool.

For full information about these tools see the User Guide.

Upgrading From Older Versions

To upgrade from a version prior to 8.2.3, first upgrade to version 8.2.3 (or later 8.2.X). Full details about upgrading from older versions can be found in the documentation for the target version.

Notes on Upgrading

Note: The information in this document is current as of the date of publication. To check for any later information, please see Trustwave Knowledge Base article Q21075.

Read the notes for all versions newer than your installed version. This list only includes information about version 10.0. For upgrade changes in earlier versions, see the release notes of each version.

10.0.7 TLS Cipher Lists: If you have manually entered cipher lists for TLS using the TLSCipherList Registry or Advanced setting, you must modify the manual cipher lists due to changes in the TLS/SSL library. See Trustwave Knowledge Base article Q21203.
Commit Scheduling/Manual commit: If Commit Scheduling is active, and you perform the upgrade outside the scheduled commit times, after upgrading all servers you must manually commit configuration to ensure all processing nodes receive the upgraded configuration.
10.0.2 Management Console edit page titles: On upgrade from earlier 10.X releases, the titles of edit pages may show as "EditTable". To fix this issue, clear the browser cache.
10.0.1 Windows Authentication: On upgrade from 8.2.X, Windows Authentication is enabled for the Management Console.
- The Windows Authentication feature of IIS must be enabled before upgrade.
- Folder permissions are retained.
10.0 Spam Types removed: The "filter by type" selection on the spam categories has been removed. The upgrade process checks for use of this selection and blocks upgrade until it is removed.
10.0 REST server requirement: The MailMarshal REST server (HTTPS configuration service) must be enabled before upgrade.
10.0 WebDAV incompatibility: WebDAV must not be enabled in IIS on the server that hosts the MailMarshal Management Console and Configuration Service websites.
10.0 Configuration Service Database Credential: On the Configuration Service Database page of the upgrade installer, you must enter an account with permission to create the new Configuration Service Database.
- You can use the Application Pool account only if the database is hosted on the Array Manager server.
- After completing installation, you can set up an Operational User for the Configuration Service Database, using the MailMarshal Config Service Admin tool.
10.0 Configuration Upgrade issues: MailMarshal attempts to upgrade the configuration as required. Certain rare issues require you to make changes in the SEG 8.2 configuration before you can complete the upgrade. For more details, please see Trustwave Knowledge Base article Q21122.

Uninstalling

MailMarshal can be installed in a variety of scenarios. For full information on uninstalling MailMarshal from a production environment, see the Trustwave MailMarshal User Guide.

To uninstall a trial installation on a single computer:

Close all instances of the MailMarshal Management Console website and helper applications such as Server Tool.
Use Add/Remove Programs from the Windows Control Panel to remove Trustwave MailMarshal.
Use Add/Remove Programs from the Windows Control Panel to remove additional components you may have installed, such as Web components or the Marshal Reporting Console.
If you have installed any components (such as the Web components) on other computers, uninstall them.
If you have installed SQL Express specifically to support MailMarshal and no other applications are using it, uninstall SQL Express.
