Simply Migrate - Migrating O365 (Archive) Data

This article describes steps on how O365 (Archive) files can be migrated to the Mimecast API using the Simply Migrate Management UI.

Creating a Connector within the Mimecast Administration Console

The first step to Migrating M365 data to Mimecast is to create a connector within your Mimecast Administration Console. This way, Mimecast can retrieve the desired data and ingest it into the Archive. The steps are:

1. Log in to your Mimecast Administration Console.
2. In the left sidebar, navigate to Services | Connectors | Cloud Connectors | Create a Connector .
3. Select the connector named: “O365 - Simply Migrate - archived mailbox / EWS support.
   
4. Select the Mimecast journal start date (This is the date on which Journaling was first configured from the M365 account to Mimecast).
5. Determine the Mimecast journal start date; this is used to determine the cutoff date for the import.
6. In the case of O365 Archive data, please supply a CSV list of the mailbox SMTP addresses that are in scope for the import

• • Determine if the addresses have archived mailboxes and if these archives must also be migrated. If this is the case, then please show it on the CSV, in a separate column with the value true or false for the associated mailbox. (See screenshot below for guidance).

Job Creation Steps

Once the M365 connector within the Administrator Console is set up, the migration continues within the Simply Migrate Management software.

From the UI, there are two ways to create jobs.

1. The first is upon initial installation. Following the wizard will guide you to selecting Exchange as a Source.
2. If the product has already been set up and initialized, you need to start the job wizard from within the Batches and Jobs view.

• • Select the Green List icon against the Batch you wish to create the jobs and choose Job Creation Wizard from the list as shown here:

Creating the Job

• You will be greeted with the Source selection. There are two options depending on the migration type.
• When migrating O365 Archive Data, opt for Exchange as the source type. Within this option, tick the O365 connector option
  • Select the connector and fill in the EWS URL.

• Supply the CSV list of the mailbox SMTP addresses that are in scope for the import. See the instructions at the top of this page for guidance.
  • Click Next.
  • The next page will present you with a list of the mailboxes contained in the CSV file / Exchange environment. As shown here.

Clicking Create Jobs will prompt you with some information and the option to select a Date filter, as shown here.

It is worth taking a moment to do a manual check that the number of jobs being created is correct and ensure you don’t require a date filter.

• At this point, you need one more click Create the jobs.
  • The gears start turning and the jobs start getting created; you will notice a tick is shown in the job status next to all the source files that have been selected.
• If you have created new jobs, they have a green tick as shown here.

Congratulations, You have created your M365 source jobs!
