Migrator for Notes to Exchange 4.16.3 - Scenarios Guide

Step 5 (if mail routing by domain differentiation): Configure mail routing domain for Exchange

Whether your organization implements SMTP mail connectivity only or full coexistence with Quest Coexistence Manager for Notes (CMN), most migrating organizations use temporary SMTP domains to route traffic between Notes and Microsoft 365. Other administrators configure SMTP mail routing with smart host servers for single-namespace environments. The routing method must be configured at both the server and user levels. At the user level, Notes person documents and AD object records are configured later in this procedure when provisioning the target AD and synchronizing the two directories.

If you are using subdomains for mail coexistence, configure the servers now as described the following procedure. If you are using smart hosts for mail routing, skip this step since you will configure the smart hosts in step 15.

The routing domains can be subdomains of the primary domain (e.g., notes.domain.com and exchg.domain.com) or completely separate SMTP domains. As long as they are unique to the respective mail systems and resolvable (via DNS or host files), they will suffice for routing. To configure routing domains:

Step 6 (only for coexistence with Quest CMN):Install and configure CMN components

Refer to the Quest Coexistence Manager for Notes User Guide to install and configure the desired components: Directory Connector, Mail Connector, and/or Free/Busy Connector.

Verify your CMN configuration by testing mail flow.

Exchange cannot route a free/busy query to Domino for a user who already has an Exchange mailbox. Exchange can route such queries only to its own Exchange mailboxes. This Exchange free/busy limitation is explained in greater detail in chapter 1 of this Scenarios Guide (see the Provisioning and mailbox creation topic under Migration to Microsoft 365).

The chapter 1 reference describes a method of provisioning Microsoft 365 that can preserve both Exchange-to-Notes free/busy queries and Exchange-to-Notes mail routing.

Microsoft restricts access to its hosted AD, and these restrictions prevent the CMN Directory Connector from supporting directory coexistence directly between Domino and Microsoft 365. But if you have a local AD, you can establish a “two-step” coexistence between Notes and Microsoft 365, as follows:

The combination of the two, run sequentially, would configure an effective directory coexistence between Domino and Microsoft 365.

Most organizations will perform a directory synchronization as part of the process to provision a local proprietary AD (in a later step, if you intend to provision Microsoft 365 from a local AD), and the CMN Directory Connector is well suited to that purpose.

Step 7: Discover Notes information

Migrator for Notes to Exchange (MNE) needs to know the location of the Notes Address Books (NABs) that will serve as data sources for the Directory Export Wizard in the next step. MNE also needs to know the Internet domains that will be used to generate the user SMTP aliases. MNE includes the following wizards to search through your Notes environment and return the necessary information:

Run these wizards to prepare for the Directory Export Wizard in the next step. See the NABS Discovery Wizard and Internet Domains Discovery Wizard chapters in the Migrator for Notes to Exchange Administration Guide for information.

Step 8: Export Notes directory data

The MNE Directory Export Wizard extracts user and group data from the Notes environment and populates the MNE SQL database and other data files with this information. Other Quest applications require this data for input values.

Run the Directory Export Wizard to capture the necessary information. For more information and instructions for the Directory Export Wizard, see the Directory Export Wizard chapter in the Migrator for Notes to Exchange Administration Guide.
