Migrator for Notes to Exchange 4.15.2 - Pre-Migration Planning Guide

About the Migrator for Notes to Exchange documentation Introduction Critical considerations Other strategic planning issues Appendix A: Known limitations of the migration process

Other non- or partial migration issues

The Highlighted text RTF format does not migrate from Notes 7 or higher. Other RTF formats, however, do migrate from Notes 7 or higher.
Archives on CD-ROM cannot be migrated. An attempt to migrate a user archive from a CD-ROM will generate this error:
User archive NSF files can be migrated from a hard drive via the file system, but cannot be migrated from a CD-ROM. If you want to migrate an archive on a CD-ROM, copy the NSF file to the migration server hard drive, and then migrate via the file system.
Image resources do not migrate: Image resources (inserted in a Notes message by Create|Image Resource) do not migrate.
OLE attachments do not migrate. But an OLE object can be migrated when embedded within the body of a message.
Notes rules do not migrate. Notes mail rules, which let individual users tell Notes how to process their incoming messages, do not migrate to Exchange except for out-of-the-office rules.
Outlook reminder pop-ups appear for migrated but unprocessed meetings that occurred in the past. Outlook displays its pop-up meeting reminder dialog box for a migrated meeting that is scheduled for a date/time in the past if the meeting was unprocessed when it was migrated. In this scenario, Outlook also adds the unprocessed meeting to the user's calendar, and marks it as tentative. This is native Outlook/ Exchange behavior.
Broadcast meetings are migrated as regular meetings. The Notes feature Do Not Receive Responses From Invitees, which makes a meeting invitation "broadcast-only," does not migrate to Exchange.
Cancelled meeting instances do not migrate. Migrator for Notes to Exchange does not migrate cancelled meeting instances, even though Notes may retain them.
ACL for disabled Notes user may migrate due to latency: A propagation delay in Notes may cause the ACL for a disabled Notes user to inadvertently be migrated when the migration occurs soon after the user is disabled. In this case the user will appear with a cryptic name such as NT- User: S-1-5-21-12354667. When the user is re-enabled in AD, after some propagation delay, the user will appear normally in the Outlook ACL.
Stationery dates do not migrate. When Notes stationery is migrated to Exchange, the date associated with the stationery becomes the day-and-time of migration.
Signature templates do not migrate: The Data Migration Wizard and SSDM migrate signatures that occur in messages, as parts of the messages, but do not migrate Notes signature templates. End users who want to use automatic signatures in Outlook will have to create them in Outlook after they have been migrated.
Message recall-ability does not migrate: A message originating in Notes and then migrated to Exchange/Outlook cannot then be recalled from the Exchange/Outlook environment.
Request update messages are not migrated. A Notes user who has been invited to a meeting or assigned a task can request information—a feature that sends a special Notes message back to the originator. These "request update" messages do not migrate.
Custom alert text assigned to a Notes reminder is not migrated. A Notes user can create a calendar entry (a meeting, reminder, or so forth), and in the Remind Me feature may create or edit a customized message to be displayed with the reminder. When we migrate this data, the text is lost because there is no comparable feature in Outlook.
A contact's briefcase items do not migrate. The briefcase folder of a personal contact may contain attachments and comments, but the contents of the briefcase folder do not migrate.
Customized field labels in Notes PAB entries do not migrate. Any contents of such a field will migrate, to whatever field in Exchange corresponds to the original field label in Notes, but the customized label does not migrate.
Dates of draft items do not migrate. A draft item (no content in To, From, Subject, body) will migrate from Notes to Exchange, but the date associated with the draft becomes the day-and-time of migration.
Table borders do not appear in some target client platforms. The table borders of tables that appeared normally in the Notes source do not appear when migrated to some versions or OWA (Outlook Web Access) and Android. Tables appear normally, however, with their borders, in Outlook 2010 and most other target client platforms.
Meeting updates are not supported between Notes and Outlook in some cases. When a recurrence pattern for a series of meetings is supported in Notes but not supported in Outlook, and when the organizer OR attendee, but not both, has been migrated, some updates/cancelations/responses for single occurrences will not work.
"Private" meeting created in DWA isn't private after migration: The "private" status of a meeting created in Domino Web Access is not preserved upon migration. Migration does, however, preserve the "private" status of a meeting that was created by a local Notes client.
Meeting invitee tracking is not accurate in some cases after migration to Exchange: If a meeting is scheduled in Notes and a Notes invitee accepts the invitation after migration to Exchange, invitee tracking is not accurate in Exchange. There will be two entries, one that is correct, and one that is not. The one that is not will always say "no response".
ACLs: ACLs can only be added for groups on mail folders if the group is a security group.
Display name of migrated Rooms: After the calendar of a room resource has been migrated to Exchange, and forwarding is set from Notes to Exchange, if you book this resource in Notes, the name of the room may appear to be changed. Due to the forwarding and a limitation on the way Notes parses addresses, the room will be referred by the left-hand side of the forwarding address and not the canonical name.
All migrated bullets look the same on ANSI Japanese systems: On ANSI Japanese systems, the Notes RTF exporter exports any bullet character as a Unicode • "BULLET", so all bullet characters in migrated messages appear the same, regardless of their appearance in Notes. (Migrator for Notes to Exchange uses Notes to export RTF from messages.)

Other Data Migration Wizard issues

Exchange provides no tracking info for invitation received in Notes but accepted post-migration in Exchange. Notes is unable to associate an accepted meeting invitation with a meeting organized in Notes, if the invitation was originally received in Notes, but not accepted until the recipient had migrated to Exchange.
Message subjects truncated: Messages with subjects longer than 4096 characters cause Migrator for Notes to Exchange to stop processing a mailbox at that message. Migrator for Notes to Exchange therefore truncates longer subjects to 4096 characters. Meanwhile, Outlook truncates any message subject longer than 255 characters to 255 characters. A message subject longer than 4096 characters will be truncated twice during migration: once by Migrator for Notes to Exchange, to 4096 characters, and then again by Outlook, to 255 characters.
Duplicate messages from multiple Notes locations: Migrator for Notes to Exchange does not filter duplicate messages that it finds in different locations in the Notes environment. For example, a message that has been deleted in Notes might appear in Exchange if it had not yet been processed by the server, so that it also occurred in some other Notes location(s).
Hidden-contact AD forwarding option doesn’t work in Exchange 2010 or later: The AD forwarding option to create a hidden contact, and attach it as the alternate recipient of the mailbox (set by [General] Forwarding- Method=0), does not work in Exchange 2010 or later. This appears to be a limitation of Exchange.
Notes user-created folders are migrated to Outlook system folders. A user-created folder in Notes that has the same name as an Outlook system folder will migrate to the corresponding Outlook system folder. Meanwhile, a Notes system folder migrates to its equivalent Outlook system folder. For example, the Notes system "Sent" folder and any user-created folder in Notes named "Sent Items" would both be migrated to the Outlook "Sent Items" folder.
When migrating only iNotes contacts, the Notes Mail Files screen does not appear, so you cannot choose to migrate via the server or the file system. The program will run via file system if that's what you chose for your last migration, unless you go into the Task Parameters or INI file and change it.
Possible problem with Symantic E-Vault migration: When migrating from a Notes environment with Symantic E-Vault, Exchange propagation issues may interfere with Migrator for Notes to Exchange setting custom attributes when the destination mailbox has never been accessed either by Outlook or by the migration application. One simple workaround would be to first run a "dummy" migration (e.g., use a date filter where date > 1/1/2100) to open all the target mailboxes before running the real migration.

SSDM issues

Outlook Personal Archive folder must be open to receive migrated items via SSDM. An end user wanting to use the SSDM to migrate items to an Exchange Personal Archive must first open the Personal Archive folder in Outlook before running the SSDM.

Before migrating data, the SSDM uses a MAPI OpenMsgStore call to open the MAPI profile's default mailbox. If Outlook has been enabled using the Active Directory Authentication Library (ADAL) and the ADAL credentials are stored in the cache, then MAPI authentication is performed using the ADAL cached credentials. If the cached ADAL credentials are not valid, the MAPI login fails and there is no prompt for credential entry.

When this scenario occurs, the SSDM migration summary window indicates “Migrated 0 objects with 2 error(s) and 0 warning(s) from your mail file”. The Error Report Log contains the following errors:

1
Click Start > Control Panel > User Accounts > Credential Manager.
2
Select Windows Credentials.
3
Locate the set of credentials that has MicrosoftOfficeXX_Data:ADAL in the name and then expand the corresponding folder.
4
Click Remove from Vault.
