Product Review – Kernel Office 365 Migration

Product Review – Kernel Office 365 Migration

Business acquisitions, as well as mergers, call for data migration between Office 365 tenants and the best way to perform this migration is via a reliable third-party tool. Here, I am going to share my experience of using a proficient migration tool meant for Office 365 migrations – the Kernel Office 365 Migration tool.

Let’s first have an overview of the prominent functions of this tool.

Highlights of Kernel Office 365 Migration 

  • Moves single/multiple Office 365 mailboxes to Office 365.
  • Exports primary mailboxes, archive mailboxes & public folders.
  • Facilitates migration between Office 365 tenants.
  • Migrates shared mailboxes and Office 365 Groups as well.
  • Quick & easy mapping – manually and using CSV file (for bulk mailbox migration).
  • Advanced filters along with folder exclusion & deleted item skipping options.
  • Offers to assign impersonation rights to user mailboxes directly.
  • Supports on-premises & hosted Exchange migrations.
  • Complete support with all Office 365 plans and Exchange versions.

You must be thinking over how a single tool can offer this much facilities. But it is quite amazing, and I would like to appreciate the work of the developers. To know more about the above mentioned features of the tool, get the demo version of the tool at https://www.nucleustechnologies.com/office-365-migration/ You will find the complete system requirements information also there.

I would like to list some of the important features of the tool, which impressed me a lot. These are:

  1. Assigning of Impersonation Rights

  2. This tool allows assigning impersonation rights to a user mailbox (both at the source and the destination) with a single click. It also provides the cmdlets for assigning these rights manually (using PowerShell).

  3. Use of CSV File for Migration

  4. On the welcome screen of this tool, you will find an option Import from CSV.

    When you click this option, it will ask to browse and add the mapped CSV file. The CSV file helps in bulk mailbox migration (in an automatic way).

    You can easily download a sample CSV file from the tool and thus fill up the details of the source and destination mailboxes.

  5. Ease of Mapping

  6. Users can easily map the source and destination mailboxes by selecting the desired destination mailbox against each source mailbox from the drop-down list. Also, users can map the source mailboxes with target mailboxes using a CSV file (as mentioned above).

  7. Migration of Public Folders/Archive Mailboxes

After mapping the source and destination mailboxes, the software provides you a choice to migrate a mailbox, archive mailbox or public folder from the to the destination (mailbox, archive mailbox or public folder). You can choose the desired option.

Pros & Cons

On the basis of my trial, I would like to give some Pros and Cons of this tool.


  • Various types of migrations using a single console.
  • Direct assigning of impersonation rights.
  • Migrates Office 365 Groups and shared mailboxes.
  • Preserves original mailbox hierarchy and meta-data of items.
  • Automated mapping and migration with CSV.


  • Trial version saves only 10 items from each folder.

Considering the pros of this tool, this trial limitation can be ignored, and, in my view, this tool is the best among the similar tools in the market.


Kernel Office 365 migration tool has many features including filters that are praise-worthy and beneficial in the migration processes. Overall, it is the best professional utility I have come across with. It offers advanced facilities and delivers precise results.
