This guide will show how to configure IMAP as a source configuration

For IMAP this is defined by the following requirements:

  1. IMAP Overview
  2. Delegated Access
  3. Migrating to Google Workspace
  4. Migrating to Microsoft 0365 Section

IMAP Overview

Select the credentials (username and password) of the administrator account within the IMAP environment. When migrating from Gmail to IMAP select less secure apps in order to gain access. IMAP will not migrate contacts and calendars this is expected behavior.

Following these prerequisites, steps are required before continuing onto the CloudM Migrate setup.

How to specify the IMAP special folders?

The following guide shows how to specify IMAP special folders within CloudM Migrate.



Step-by-step guide

When migrating from a Generic IMAP system, you must specify the name of several special folders in CloudM Migrate. This needs to be done to ensure that migrated messages end up in the correct destination folders when items are migrated. The setting to specify special folders can be found in the ‘Generic IMAP Source Platform Migration Settings’.


If your IMAP server does not support one of the special folders, please leave that setting empty


You should specify the special folder names as they appear in your system. These settings may differ between IMAP servers.




Listing IMAP Folders

A useful utility has been provided under ‘Tools->IMAP->List IMAP Folders’. When the IMAP server configuration settings are complete, this tool can be run to list the folders for the test account name. From this list you should be able to identify the special folders as they appear in your system.



Mapping Original Values

When you have listed the folders from your IMAP server, you should then map them, manually replacing the "Value" in the 'IMAP Special Folders Names' list above.


Delegated Access

An account must be designated as a synthetic admin account by granting delegation rights to all other mailboxes in scope for migration.

Select Advanced Settings and under the Authentication section, select Credential Method and change it to Delegated Access.

In the Admin Username field, enter the account that has been giving delegation rights.

Setting up delegated access.

Migrating to Google Workspace

These steps should be completed in the Destination environment.

When migrating to Google workspace, review the Google Workspace Prerequisites
Google Tenant  Configuration

Select the user’s full email address within the Export Name field. If already created in Google Workspace, users then select their username. If the provider does not support delegated access or application impersonation, Then select then user’s passwords in the Password field.

If this fails validate the information has been entered correctly.

Migrating to Microsoft 0365 Section

For Microsoft as the destination, refer to to the 0365 Tenant  Configuration

When migrating Microsoft as the destination, please follow the 0365 Configuration.

CloudM Migrate will perform a connection test against the destination O365 tenant.

If this fails, validate the information has been entered correctly.
