HCL has recently acquired IBM Notes and several associated services too. Some of the services like SmartCloud went down and others will go offline gradually. It is the high time that businesses move to a more beneficial platform like Office 365 which has zero maintenance, greater security, and larger number of applications. If you are still using IBM Notes, then you can jump to Office 365 along with existing information with the help of this article.

HCL Notes to Office 365 migration

HCL Notes user-interface is quite difficult to operate. So, it is not suitable for novice and non-technical users. It is expensive to purchase, install, maintain. Users need to purchase it individually as it is a standalone application. Many have complaint of synchronization issues between Notes & Server as well which has convinced many HCL Notes users to migrate to Office 365. Also, Office 365 provides more benefits and services than HCL Notes such as less RAM storage, large cloud storage, support to VoIP and PBX technologies, integration of collaboration tools like SharePoint, OneDrive, Skype for Business, Yammer, Teams, etc.

For the users of IBM SmartCloud Notes, since HCL has taken over the collaborative products in IBM’s portfolio, it is going to end the Softlayer Infrastructure under which the SmartCloud Notes comes. So, SmartCloud Notes users also have to migrate to other cloud platforms like Office 365 ultimately. For migration, they can follow the same process as HCL Notes to Office 365 migration.

Migration from HCL Notes to Office 365 manually with IMAP Connector

One can migrate from HCL Notes to Office 365 or Exchange manually with the help of IMAP Connector. Below mentioned are the steps for HCL Notes to Office 365 migration:

  1. Backup NSF files
    First of all, backup your HCL Notes NSF files. In case your migration fails and NSF files get corrupt during the migration, you can recover the mailbox data from the backup taken earlier.
  2. Create new Mailboxes for each NSF user
    Now, create new mailboxes at the Office 365 location (with same name as in IBM Notes) for each user who has an account in HCL Notes.
  3. Enable IMAP TCP/IP port

    First, you need to enable the IMAP TCP/IP port for each user account. Just follow the steps mentioned below to do the same:

    1. Open Domino Administrator in the Lotus Notes Application.
    2. Go to the Configuration tab.
    3. Open the Server document which executes the IMAP service.
    4. Click Ports>Internet Ports>Mail tab.
    5. In Mail (IMAP) column, change the ‘TCP/IP port value status’ to Enabled.
    6. Click the Save button to save the changes.
  4. Synchronize with IMAP Connector
    Finally, use IMAP connector to synchronize mailboxes between Lotus Notes and Office 365. There should not be any issue in the connection now.

Drawbacks of Manual HCL Notes to Office 365 Migration

The manual migration process has many drawbacks just like any other manual method-

  • The firewall and proxy server of HCL Notes may block the internet connection.
  • NSF files which are more than 1 GB in size are not migrated
  • Calendar items have to be migrated manually as this method does not support its migration
  • It is quite a lengthy and time taking process.
  • Allows migration of 15 mailboxes in one go.
  • Higher chances of different structure, properties alteration, data loss, and incomplete migration.
  • Only a technical expert can perform the migration without any hassle

Note: Another method to move NSF data to Office 365 platform is exporting it to the CSV file format using the Export feature in the Notes application and then importing the CSV file into the Office 365 platform using the Network Upload method which includes the use of SAS URL and AzureAz Copy tool. This method is not recommended and explained since it is complex, lengthy, suitable for only emails, and fails most of the times.
