If you are storing Drive document mappings and running a large migration, contact the support team.

Required ports

Primary and Secondary servers will communicate with the source and destination platforms, and the CloudM Migrate licensing platform using HTTP/HTTPS. Therefore ports 80 and 443 will need to be open between these environments

The URLs accessed for the license server are as follows.

  • portal.thecloudmigrator.com
  • tracker.cloudm.io
  • migratortracker-hrd.appspot.com

There is also the following to consider:

  • SQL server runs on TCP 1433 and UDP 1434 - SQL server needs to be installed and set to TCP or UDP on the Primary/SQL Server. For information on setting the TCP to 1433, refer to this following article.
  • Redis runs on port 6379
  • gRPC on the below TCP ports. Note: It is possible to customise these ports when installing via Command Line using the instructions here: Installing / Upgrading from the Command Line 
    30061 (Primary Service)
    30062 (Secondary Service)
    30063 (Results Logs Service)
  • All of Google's API endpoints are listed here: https://support.google.com/a/answer/60764
  • All Microsoft 365 URLs and IP address ranges are listed here: https://docs.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide

CloudM Migrate Hosted

CloudM Migrate Hosted makes migration as simple as possible. There are no system requirements or installation, you can simply access the Hosted migration platform and configurations are pre-provisioned. See here for more information.

Platform prerequisites

CloudM Migrate only supports migrations from HCL / Lotus Notes version 10 and earlier.

The following software should be installed on the migration workstation:

  • HCL Notes client, version 6.0.2 or higher (up to HCL Notes version 10). The client installation should be compatible with the server installation

You will also need:

  • The HCL Notes/Domino server address
  • Administrator username. The username is usually in the format Admin/ORG
  • Administrator password
  • Administrator Notes ID file

Source Platform prerequisites

Service Access to Mapped Drives - If you are using the web version of CloudM Migrate or a multi server setup with secondary servers and want to migrate NSF files that are not on the Notes server and will be accessed directly from the file system then you should make sure that the CloudM Migrate service has access to mapped drives if the files are located there. Please see the article on making mapped drives available for more information.

Logging into the Notes Client - You must log into the Notes client on all servers where the migration will run when logged into the server as the specified Windows User and with the Notes Administrator username and password. Note Client should be closed after logging in. Failure to do this will result in permission issues when opening the Notes ID file.

Source Platform Settings

Choose Lotus Notes as the migration source and enter your HCL Notes (Lotus Notes / IBM Domino) settings into CloudM Migrate and then click Next.

Multi-Server configuration and network access - In a multi-server configuration, it is vitally important that the Master and Secondary servers have full network access. In some scenarios, this may require configuring proxy settings through Internet Explorer by clicking Tools > Internet Options > Connections > Local Area Network (LAN) settings to allow access.

Server Details

  • Server Address – The hostname or IP address of the Lotus Notes server.
  • ID File – The path to the Administrator's Notes ID File.

Client Authorization Settings

  • Admin Username – The abbreviated name of the administrative user that will be used to perform migrations. This should be of the form ‘Administrator/ORG’
  • Admin Password – The administrator’s password. This should be the password that can be used to access Notes using the ID file of the administrative user, who should have previously logged into Notes from the migration workstation.

You must log into the Notes client on all servers where the migration will run when logged into the server as the specified Windows User and with the Notes Administrator username and password. Failure to do this will result in permission issues when opening the Notes ID file.

Windows Authorization Settings

  • Windows Username – The username of the Windows User the Notes migration should run as (normally the same as the currently logged in user).  Specify domain\username if required.
  • Windows Password – The password for the Windows user.

Resource Database Details

These settings can usually be left at the default settings unless special customization is required based on your Notes infrastructure.

  • Resource Database – The name of the server database containing resources. If there are no resources, please leave this setting empty.
  • Resource Views – The views within the resource database containing resources.

User Database Details

These settings can usually be left at the default settings unless special customization is required based on your Notes infrastructure.

  • User Database – The name of the server database containing users.
  • User View – The view within the user database containing users.
  • Import Name Attribute – The name of the attribute used to generate the ‘Import Name’ field in the user list. Only the name part of any email address is used.

Configure Destination Platform Settings - Google Workspace

Select Google Workspace as your destination platform.

Select where you would like your data to be migrated. If you have purchased Google Vault, you may want to migrate data directly into Google Vault.

To enable Google Vault for your domain, please see this article

Destination_Platform_G_Suite.PNG Select Add Settings.

Enter information for your Google Workspace admin account.


  • Domain Name - The domain name you will be migrating from. This should be the Internet domain name, not the local domain name.
  • Admin Username - An administrator account for the domain specified, this will usually be an email address for a Super Admin.
  • Authentication Method - Set whether to use a P12 key or a JSON key as the authentication method.
  • Service Account Email Address - Before attempting to configure CloudM Migrate, you should have created a Google Cloud platform project and created a service account for it. If you have selected to use a P12 key, you will need to input the service account's email address in this field.
  • Private Key - The file path to the P12 or JSON key that was generated and downloaded when creating the OAuth service account.
  • All Advanced Settings are set to a default value, designed to ensure that your migration will work without additional configuration. You should only edit the Advanced Settings if instructed to by CloudM Support or in a CloudM Knowledge Base article.

Select which items to migrate

It's now time to add which items you'd like to migrate.


To add the items from that you want to migrate from your source platform to your destination platform, select Add items to migrate drop down menu and click on one of the following options:

  • Get Items from source - Get a full list of all items in the source platform.
  • Bulk add / import items - Upload a CSV file to bulk add users.
  • Add User/Resource/ Group/Shared Drive/Team Site/Microsoft Team etc.- Manually add an item of the selected item type.

Selecting a Star next to any specific user or users will prioritize their migration. When a migration starts, threads will be assigned to any starred user first so that their migration can start immediately. 

At this point you can choose what to migrate for each user, you can migrate Mail, Contacts, Calendars, Tasks, Classic Sites, Notes and Channels.

Enter your user's full email address within the Export Name field. If you have already created your Microsoft 365 users, then you will just need to enter their username.

Select how much content to migrate

CloudM Migrate lets you decide how much content to migrate to your domain by specifying required date ranges. 


If you are changing your email address as part of the migration you can verify that the domain names are correct here. You can also specify specific Address Replacements in the respective section of the advanced settings.

Environment Scan

Environment Scan allows you to plan and prepare your migration by performing analysis of your source file and mail environment and reporting important information such as item counts, data volume, permissions, and folder depth.

Reports are produced which can be exported and analysed. Using the information provided you can estimate your migration's duration more accurately, and address any potential issues before your migration even begins.


Selecting Scope of Scan


Depending on your source platform, you can choose to scan files, emails, or both sets of items.


  • Leaving the Report on File Permissions setting unchecked will speed up the Environment Scan process.
  • In order to include Report on File Permissions in the process, you will need to check this setting AND enable Document Sharing (or a setting related to document sharing) in the Source Platform settings. If either is not enabled, the Environment Scan will not scan or report on File Permissions.


Your CloudM Migrate userlist is used to define the scope of the scan. You can choose to scan all accounts from your list, or restrict the scan to users selected for migration.


How to run an Environment Scan

After entering your source and destination server settings, populating your userlist, and configuring your settings, you will be prompted to run an environment scan. It is optional, but recommended for file platforms.

Click Start and then confirm by selecting Start Environment Scan on the pop-up box to begin the scan. CloudM Migrate will connect to your source environment and capture file and / or mail information. This can take up to several hours, depending on the amount of data present.


Once the scan completes, the data is reported on the Environment Scans page and can be exported to file, using the Export Scan Results option.


Start your migration

To begin your migration, select Start.



Review your migration results

During the migration process, CloudM Migrate will report back in real time exactly who is being migrated and the items being processed. All you now need to do is sit back, relax and wait for your migration to complete.

Check the progress of your migration.

Once complete you can download a full report for your migration.

Delta Migrations

CloudM Migrate supports delta migrations of all migration types. To run a delta migration after the first pass, simply start the migration again. Already processed mailbox items will be skipped, and file items will be checked for changes and re-migrated if updated since the previous run. More info:
