Overview: How to migrate Lotus Notes to Office 365? This article discusses all aspects of this migration process including the benefits of Office 365 over Lotus Notes and the best method to complete the task.

Microsoft Office 365 has proven to be a superior business productivity solution in every sense. The convenience offered by this service is too beneficial to be overlooked now.

This is why Office 365 has become the most prominent choice for organizations switching from other email clients and productivity solutions. One of those email clients is Lotus Notes.

Why Migrate Lotus Notes to Office 365?

Office 365 stands above Lotus Notes because of the lost list of attractive features it offers. Office 365 offers a plethora of result-oriented features in a simplified user interface.

Lotus Notes offers impeccable security but, the user interface is highly complex and not at all easy to use. On the other hand, Office 365 offers a user-friendly and intuitive interface with other useful features. 

If the organization decides to migrate from Lotus Notes to Office 365,  it would further save maintenance and infrastructure costs. The subscription plans offered by O365 are highly scalable and suitable for small as well as large businesses which makes it an ideal choice for businesses of every size.

Solutions For How to Migrate Lotus Notes to Office 365

Here, we include the best two approaches for performing this migration. One is a complex and time-consuming manual approach and the other is an automated professional approach to simplify the migration process.

Method 1. Use MONTI to Migrate Lotus Notes to Office 365

Microsoft Online Notes Inspector (MONTI) was developed by Microsoft. This tool is specially designed for the customers to gather the required data to perform migration manually. This tool collects multiple information such as calendar item size, mailbox size, group item size, and contact item size as well.

The administrator should be able to create replicas on the Domino servers and right to execute the remote console commands to the Domino servers. You need to follow some steps.

  • Step 1. Download and double-click on the MONTI.exe.
  • Step 2. Then a wizard opens to Browse its location.
  • Step 3. Click on Browse to finalize the destination location and hit the Unzip button.
  • Step 4. Now all the documents are installed in the defined location.
  • Step 5. Go to the installed location and then open its guide and start performing its steps.

Limitations

  • Administrators should have complete server knowledge, any of the mistakes can affect the data.
  • There are 86 pages in the MONTI migration guide, which is difficult to read and implement.
  • To work the long manual and execute each step is difficult.
  • There is no guarantee that data will be migrated successfully without any error.

Method 2. IMAP Connector to Perform Migration

HCL Lotus Notes provides the facility of an IMAP connector to migrate the data successfully to Office 365. This is another manual method. Let’s explore its steps.

Step 1. First, you need to take the backup of the NSF files. Because there are chances of data loss while performing the migration manually.
Step 2. Now Open Office 365 and create the mailboxes for the users as per in the Lotus Notes.
Step 3. Enable IMAP/TCP Port for all users, to do so, you need to follow some steps.

  • Open the IBM Notes and then Domino Administrator.
  • Next, go to the configuration tab.
  • Open the Server document to run the IMAP service.
  • Now navigate to Ports > Internet Ports > Mail.
  • Enable the IMAP TCP/IP Port status.
  • At last, click on Save and Exit.

Step 4. Connect with the IMAP Connector for the synchronization of emails in Office 365.

Limitations

  • Enabling the Firewall and Proxy in Lotus Notes blocks the Internet connection.
  • It does not have any option to migrate the calendar entries. You need to do this manually.
  • Using this method you can only migrate the NSF files to Office 365 which are in 1 GB only.
  • It requires technical knowledge to use this method, there are a lot of filters that need to applied which makes the process complex and expensive as well.
