Multi-workload Migration :


Migrate workloads into & around Microsoft 365

Whether you want to migrate tenant to tenant, restructure workloads, move on-premises into the cloud, consolidate non-Microsoft sources such as Box, Dropbox and Google Drive, or migrate Slack to Teams, our hosted migration services have you covered.

Opt for a DIY approach supported by our migration experts or let us look after everything for you.


Take a best practice, phased approach to your migration project:

Facilities team reviewing new office plans

Understand what you have

Get the data you need to plan a smooth migration:

  • Profile your existing information architecture, data size, users & site activity 
  • Find out what’s important, or just collecting dust
  • Identify any customisations, checked out files & workflows that may impact your migration

You are now ready for the next stage:

Plan & design your migration

  • Filter according to properties or metadata
  • Exclude content, such as neglected sites
  • Selectively include or exclude objects (webparts, navigation, Apps, views, etc.)
  • Map any required restructuring
  • Convert mailboxes, e.g. to shared mailboxes
  • Convert Teams channels, e.g., standard to private.

Execute your migration

  • Stage & timetable your migration to ensure a seamless UX
  • Migrate TBs a day
  • Use Azure BLOB storage to minimise throttling
  • Preserve permissions, version histories, sensitivity labels & more as you move
  • Complete final Outlook config tasks & guide users through any final migration steps

Monitor progress as you move

  • A real time dashboard lets you track progress
  • Detailed reports validate what’s been moved: volumes, sites, lists, libraries, item counts, etc.
  • Keep stakeholders automatically informed
  • See all actions & any errors in one overall view
  • Re-run any stopped or failed jobs
  • Understand migration trends.

Many different sources & platforms supported

  • File shares
  • OneDrive
  • Exchange on-premises & online
  • SharePoint sites, individual lists & libraries
  • Teams Instances, Channels & Chats
  • Non-Microsoft sources e.g., Box, DropBox & Google Drive

What our customers have to say

“Although shortcuts would still work across the network after migrating to Microsoft 365, the prospect of maintaining a dedicated email archive on-prem was a non-starter. Essential worked out the best strategy for migrating our archived emails into Exchange Online.”
