It’s understandable the logistics of merging two organizations together could be pretty tricky. This pertains to moving data at work 365 or merging tenants. It’s very easy for data and users to explore the shuffle when the proper planning and validation procedures aren’t set up at first. To really make the process as smooth as you possibly can, continue reading for quick tips to moving Office 365 data during acquisitions and mergers!



Firstly: Being an admin, you have to choose which tenant is moving where. Sort out all your licensing with Microsoft. Think about the next:

  • Which licenses do your users have?
  • What Microsoft workloads are the users using (Teams, Groups, SPO, EXO, etc.)?
  • Does your destination tenant have a similar workloads setup and proper licenses?

The next thing is to choose a competent migration oral appliance run pre-discovery. Pre-discovery provides you with a feeling of just how much content you’ve,  what kind of content you’re dealing with, and just how “fresh” is the data. According to that, you are able to check out your atmosphere and discover what you’re likely to move, just how much you’re likely to move, where it’s likely to be gone to live in.

The greatest merger and acquisition-specific step to consider is naming conventions between domains. An excellent migration tool will help you to import names and personalize them as data moves, but it is also important to actually have a very good feeling of exactly what the domain structure appears like within the source and just what it might seem like within the destination.

Consider: Would you like users to achieve the same titles within the old domain because this one? Could they be just altering domains within their emails, i.e. map to How about service accounts? Are you currently moving all users or simply active employees?

Build Connections

Getting an association together with your source system, whether it is Office 365 or anything else, is essential. This connection enables you to get a complete-fidelity pre-discovery scan. Additionally, you have to develop a link with the destination, which will really move your articles to your new tenant. These connections should have all of the access they require on the origin and also the destination.

We advise always utilizing an application profile for moves to/from Office 365 this helps to ensure that you’re following MSFT guidelines and moving your computer data as efficient and fast as you possibly can. and configuring something account within the odd situation you will find stuff that can’t be retrieved by the application profile).

Now it’s time to construct an agenda for transitioning users and moving the information. Naturally, there’s some user management that should happen when moving tenants. You do not would like your users to simply awaken eventually and find out all of their documents shifted to a different tenant, possess a new current email address and become missing and have new workloads enabled. The primary objective of migration planning would be to help mitigate any disruption for your finish users and permit them to feel ready for the switch.

Take application compatibility between tenants, for example. If the organization that acquired your business uses Microsoft Teams however your organization doesn’t, it’s necessary to fully train your users on whatever new workloads are for sale to them within this new publish-merger/acquisition world. Should there be new governance rules that must definitely be learned, attempt to introduce individuals in early stages to help make the transition as smooth as you possibly can.

Similarly, if it is reversed as well as your organization continues to be utilizing an application the other hasn’t, what goes on to that particular data when you merge? Whether you choose to archive it, pull it offline, or move it to your destination tenant, it’s best to possess a arrange for these migration hurdles in the start.

After you have organized an agenda to maneuver users as well as their content, we recommend first moving nearly all user content to the destination utilizing a full migration, then allowing a transition period when there’s some overlap and users’ get access to both tenants. After that you can perform an incremental migration to softly bring over any loose ends or changes before a person is fully cut to the brand new tenant.

This may be a gradual process that’s frequently performed in groups. With respect to the size the merger or acquisition, I suggest doing the work by department. Perform a pilot first with a few friendly folks who’re prepared to test things by helping cover their you.


Some migration jobs may not get everything to begin with, so it’s fundamental to do analyses on all jobs that don’t fully complete (i.e. jobs that filled with exceptions or simply plain fail). These exceptions and failures could be as a result of large number of factors for example:

  • Connection problems
  • File types
  • Size limits
  • API limitations (likely around the source side)
  • And much more

It’s highly suggested to completely understand any limitations which are printed on the origin and destination side. Oftentimes they are from your control or those of your tool vendor, so this helps set the expectation with management in the start of your migration project.

Think about the “move” a continuing loop before the project is finished and make sure that you arrange for some content requiring a couple of passes before everything will get fully moved. Submissions are going to alter if users are active, and that’s okay!

Before you decide to report that you’re fully migrated, make certain you make sure all of the content that may be moved went through effectively. Third-party reporting tools could be useful by directly suggesting what’s moved and why something hasn’t moved.


Finally, you usually wish to validate that everything came over and review any errors that might’ve happened throughout the move. This validation process can help you catch and manage something that might’ve tucked with the cracks and bear out any lingering incremental migrations that should be taken proper care of.

Note: This method goes more easily if users are educated to validate their very own data publish-migration. This is also true if any type of data transformation has happened.

Common Pitfalls to prevent

Not planning change management together with your users

Again, don’t just move your users overnight without one knowing it’s jarring and can make modifying towards the new tenant that rather more difficult. If users enter into work and magically have new workloads they didn’t have contact with before, or maybe it normally won’t possess a workload that there used to be, it’ll only cause issues.

For this reason managing your users and planning your migration is really important. A vital success element in any migration is making certain minimal disruption for your users’ workday, and it could make things much smoother if they already know their technical team is respecting that!

Not giving yourself lots of time to migrate everything

Moving content should not happen during working hrs. Ideally, schedule the roles so they run overnight or over the past weekend. This not just aligns with guidelines from Microsoft, but keeps your users’ tenants running at full capacity throughout the workday. After that, it’s vital that you figure out how lengthy something is really likely to take within individuals limitations. For those who have 100,000 workers to maneuver, the number of are you able to feasibly relocate confirmed time period? Attempting to squeeze a considerable migration right into a short time is only going to have unwanted effects, for example:

  • Disrupted users
  • A slower tenant if an excessive amount of throttling occurs
  • Possibility of “missing” content if there is not lots of time to remediate errors or perform validation
  • Insufficient runway to organize users for what’s new or not far off
  • And so forth

If you have a good deadline, try moving priority content first and just very necessary data (i.e. content that’s considered “active”).

Though moving Office 365 data throughout a merger or acquisition could be tricky, I really hope this short article helps to make the process go a little smoother. Even though you’re planning your migration, have you contemplated how you’re likely to manage the gradual increase of recent users? What’s the obtaining company doing to make sure that the folks, content, and workloads arriving have been in alignment using the obtaining company’s governance plan?
