Summary: If you plan to migrate IBM Lotus Notes to Microsoft 365, use an NSF to PST converter software, such as Stellar Converter for NSF (downloadable below) or Microsoft Online Notes Inspector (MONTI). In this guide, we have discussed four different methods in detail to help you with the NSF to Office 365 migration process.
Microsoft 365 has gained popularity in the recent past due to several benefits it offers over email platforms, such as HCL Note, formerly known as IBM Lotus Notes. Both small and large businesses are now migrating to Office 365 from other platforms, especially those using IBM Lotus Notes. This is because managing Lotus Notes is not only difficult, but it also lacks several features.
Office 365 provides a collaborative environment where users can cooperate with their team members or customers and communicate better with Skype for Business that comes with Microsoft 365. Moreover, users can access and work from anywhere as Office 365 is cloud-based and available for mobile devices.
Overall, Microsoft 365 handles emails and performs other tasks significantly better. However, migrating IBM Lotus Notes (HCL Notes) data items stored in NSF file formats to Office 365 requires the necessary technical skills to execute the transfer process properly, minimize downtime, correct evaluation of data that the user wants to migrate, and most important avoid any data loss situation.
This blog covers various methods to migrate Lotus Notes to Microsoft 365 (Office 365). Follow the one you find most suitable for your need.
Methods for Lotus Notes to Office 365 Migration
Following are the methods to migrate IBM Lotus Notes to Office 365.
Method 1: Migrate Lotus Notes to Office 365 using MONTI
Microsoft Online Notes Inspector (MONTI) is Microsoft?s official guide to migrating Lotus Notes to Microsoft 365 or Office 365. It?s an 86-page long guide that explains the entire process of Lotus Notes to Office 365 migration. You can download the MONTI.exe file from here.
- Once downloaded, double-click on the MONTI.exe file and click ?Browse? to choose a save location on your system.
- Then click ?Unzip?. This will extract the MONTI documents to the selected location.
- Navigate to the folder location and go to Office 365 Deployment Tools\MONTI\Docs folder.
- Now open the MONTI 3.2 Configuration Guide and read it to learn Lotus Notes to Office 365 migration process.
This process is quite overwhelming, and not all users can execute this. It will take a lot of time to understand the documentation, and you might end up making errors or losing data in the process. However, if you still want to try it, read the documentation carefully and understand it fully before proceeding with the transfer.
Alternatively, you may follow the much easier methods explained below for Lotus Notes to Microsoft 365 migration.
Method 2: Use the IMAP Connector for migrating Lotus Notes to Microsoft 365
Using IMAP Connector in IBM Lotus Notes is another way to migrate IBM Lotus Notes to Office 365. You can employ this manual method when you want to move your business communications to Microsoft Office 365. Follow the four steps as explained below:
Step 1: Create a backup of Lotus Notes NSF files
The first step is to create a backup of all existing users? mailboxes stored as NSF files. Creating a backup before migration is necessary to avoid data loss, which may occur due to discrepancies during the transfer procedure. You can create Lotus Notes archives for backup.
Step 2: Create new mailboxes
Once you have created a backup, the next step is to create new mailboxes for every user having an existing profile in the Lotus Notes desktop email client.
Step 3: Enable IMAP TCP/IP Port for all users
The third step is to enable IMAP for all users. To do so, follow the steps below:
- Open Domino Administrator in IBM Notes.
- Next, click on the Configuration tab.
- Open the Server document for the server that runs the IMAP service.
- Click the following tabs sequentially: Ports ? Internet Ports ? Mail tab
- Enable the default IMAP TCP/IP Port. To do so, you will have to alter the ?TCP/IP port value status? to ?Enabled? in the Mail (IMAP) column (By default, the IMAP clients get connected to TCP/IP port number 143 on the Domino server).
- Finally, click on ?Save?, and then exit.
Step 4: Connect with IMAP Connector
Lastly, use the IMAP Connector to synchronize emails in Office 365 from the Lotus Notes email client.
Once you execute all four steps, migrating to Office 365 environment from Lotus Notes becomes possible. However, this procedure involving IMAP Connector is not without its limitations.
Limitations of IMAP-based Migration Method
The Lotus Notes to Office 365 migration using IMAP Connector bears the following limitations:
? If the Notes client is behind the firewall and proxy, it will not connect to the Internet.
? If the Lotus Notes email client is disabled, it will not permit an IMAP connection.
? If the IMAP Connector restricts the transfer of calendar entries, one must perform it manually.
? The manual creation of calendar entries takes more time and slows down the transfer process.
? The migration with the use of IMAP protocol moves only online data to Office 365.
? The IMAP Connector can move emails of a maximum 1 GB size.
? It involves applying various filters that are costly and complex.
Method 3: Lotus Notes to Office 365 Migration using NSF to PST Converter Tool
The methods explained above (Method 1, Method 2) have their limitations and can?t be performed by just any user. It requires technical expertise and an understanding of Office 365 or Microsoft 365 and IBM Lotus Notes to execute the process successfully. Moreover, these methods aren?t feasible if you migrate multiple accounts or mailboxes from Lotus Notes to Office 365.
Thus, if you want to migrate single or multiple mailboxes on Lotus Notes to Office 365 seamlessly, use a 3rd Party tool such as Stellar Converter for NSF Technician.
