About this session
• The case used is a Lotus Notes migration to Office 365
• However, information given here applies to all migrations to Office
365, both Notes-2-O365 as Exchange-2-O365
• Information given here is based on our experiences and best practices
The case
The case
• Company has used Lotus Notes for over 14 years and wants to
migrate to Office 365
3700 Notes users
1100+ applications
(700 unique applications)
7.5+ Tb of mail data
30+ domains
50+ servers
20+ datacenters
Migrate - 1 central domain
- < 3000 users
- < 300 applications
5 Notes domains
The case (2)
• MessageLabs was used for mail filtering and needed to be included in
the mail routing of the co-existence phase
• AD was not yet centralized.
• All (regional) domains needed to be consolidated to one domain:
<domain>.com
• Extra complexity: Notes is not linked to AD! Notes users needed to be
matched with an AD-account
Session build up
Why this session?
• Migrating to O365 is all about preparation and planning
• Some preparations have long lead times. They mess up any planning
• The next part of this session will be about the right order and steps of
migrating to O365
Preparations
Preparations : 1. Add local internet break-outs
Internet
Local internet break-out
Central DC
Local DC’s
Implement:
- Traffic shaping (preferably level 7)
- Firewall
- Intrusion detection
Warning: Local
internet break-out
can take up to 6
months to realize
Preparation: 2. Check and prepare tenant
Preparations : 3. All users to one central AD
<domain>.de
<domain>.nl
<domain>.fr
<domain>.it
<domain>.de
<domain>.nl
<domain>.fr
<domain>.it
Preparations : 4. Install Exchange 2013 Hybrid
server on-premises to implement AD schema
On-premises

Preparations : 5. Build ADFS-farm
Preparations : 6. Build e-mail migration farm
Staging server
CMT Controller
(EMM)
CMT Worker CMT Worker CMT Worker CMT Worker CMT Worker
Replication
Domino servers
Exchange Online (O365)
Mailbox migrations
will run at max. 0.5
Gb p/h.
Add more workers
to increase overall
migration speed Use staging server to centralize
data to DC with best
connectivity.
NOTE: Staging server and
migration farm should be in the
SAME DC
Preparation: 7. Clean-up source environment
• By very thorough cleaning we could remove / archive:
• 704 Notes users
• 400+ duplicate applications
• 300 obsolete applications
• 7 Notes servers
• Or… have over around 25% less to migrate
• By limiting the mail migration to items from 1-1-2013 and up, we
saved around another 15%.
Migrating users
to Exchange Online
Step 1: Enable all users in local Exchange
Mail-enabled user
<domain>.com &
<domain>.nl
In Exchange Online GAL
(no license assigned)
Enable as “mail
enabled user”
<domain>.com
DirSync
Match Notes-user with
AD-account and add
new external address
<domain>.com
Internet
Exchange Online
On-premises mail
Symantec Cloud (MessageLabs)
*.*
*.*
<domain>.com
<domain>.eu
<domain>.com
<tenant>.onmicrosoft.com
Internet
Exchange Online
On-premises mail
Symantec Cloud (MessageLabs)
*.*
*.*
<domain>.eu
<domain>.com
<tenant>.onmicrosoft.com
<tenant>.onmicrosoft.com
Notes (MX: <domain>.nl)
Step 2: Select user batch to migrate
Office 365 (MX: <domain>.com,
Hosted by Symantec)
User1
Primary : user1@<domain>.nl
Secondary : user1@<domain>.com, user1@<domain>.eu
User1
(mail-enabled user object)
Address : user1@<domain>.nl
Forward: user1@<domain>.eu
User2
Primary : user2@<domain>.nl
Secondary: user2@<domain>.com, user2@<domain>.eu
User2
(mail-enabled user object)
Address: user2@<domain>.nl
Forward: user2@<domain>.eu
Notes (MX: <domain>.nl)
User2
Primary : user2@<domain>.nl
Secondary: user2@<domain>.com, user2@<domain>.eu
Forward : user2@<tenant>.onmicrosoft.com
Step 2: Select user batch to migrate
Office 365 (MX: <domain>.com,
Hosted by Symantec)
User1
Primary : user1@<domain>.nl
Secondary : user1@<domain>.com, user1@<domain>.eu
User1
(mail-enabled user object)
Address : user1@<domain>.nl
Forward: user1@<domain>.eu
User2
Primary : user2@<domain>.nl
Secondary: user2@<domain>.com, user2@<domain>.eu
User2
Primary : user2@<domain>.com
Secondary : user2@<domain>.nl
Forward: user2@<domain>.eu
From: user1@<domain>.nl
To: user2@<domain>.com
Subject: …

Migrating
applications
Migrate
• We had 4 categories for applications:
• To be deleted:
• All applications that contained (almost) no content
• To be centralized:
• All applications for the content needed to be preserved for archive purposes
• To be migrated:
• All applications for which an owner is known and he / she indicated that the applications
needs to be migrated
• To be archived:
• All applications that have not been accessed for the last 6 months. Will be deleted after
1 year
• Also: The “Lost & Found”-section. If owner is not found and the application is not
accessed in the next three months, it will be a “to be archived”-application.
Migrate
Step 1: User matching
• Users need to be present in O365 before migrating
• We matched based on the following hierarchy:
• But still dozens of users needed matched by hand….
Domino Person field value Local AD user object attribute
1. internetaddress mail
2. DisplayName DisplayName
3. Firstname.Lastname CommonName
4. Shortname SamAccountName
5. DisplayName CommonName
Migrating 3000 users and 1100 applications from Lotus Notes to Office 365
Step 2: Determine app-type
Publish news procedures,
“who is who”, etc
Collaborate on products
and projects with an end
date
Contract management,
quality management
and project sites
Business
Applications
Intranet
Store personal documents,
share documents, access to
group documents and
SharePoint sites
Knowledge sharing across
departments
Communities
Central
workplace
Video portal.
Central storage
for video files
Combining trending
documents from other
office 365 systems like
OneDrive and SharePoint,
Word, PDF and e-mail
attachments
Replacement for
department sites and short
term projects
Documents, e-mail, Skype,
Messaging and calendar
Collaborate
Smart
aggregation
Media
Migration Farm
Step 3: Migrate using migration farm
Step 1: Match Notes user
with AD user and keep
static conversion list
Step 2: Analyze applications and
determine destination templates

Step 4: Manual migration
• All apps that cannot be migrated by migration software are candidate
for manual migration.
• For this we use 4 scenarios
1. Convert to COTS platform (Dynamic CRM, SAP, etc.)
2. Functional rebuild with content migration
3. Functional migration, no content migration
4. Complete rebuild
Lessons learned
Lessons learned
• Always use a Exchange Server in Hybrid configuration in your setup
• Start early with preparations:
• Local Internet-breakout & Site-2-Site VPN with Azure
• Getting the tenant right (location, licenses, name)
• Use layer 7 traffic shaping to control the download of Outlook offline cache
• Do a very thorough clean-up of data before you start
• Filter between “Need to migrate” and “Better to rebuild” (i.e. Rooms / Resources
/ Groups / Apps)

Editor's Notes

  • #28: PowerShell by Marzel Laning
  • #29: When we started, Office Groups, Delve and the video-portal where not released. During the project they were, creating a multitude of problems, especially Office Groups. They could not be disabled at first and an admin has little control over them. I.e. Minimal Viable Product. What happened at some point: A secretary made an office group with her as the single admin. She left the company and her account was deleted from AD. At that moment, no one could manage the Office Group anymore. We had to recreate the account via AD, DirSync. Login as the secretary and add new admin-account. Yammer does not have any public interface by which you can you migrate data by impersonation. Because of this, we only restarted discussions in Yammer
