Words of warning: if you are a non-technical user, skip the manual method. And check the recommended and effortless way for Office 365 tenant-to-tenant migration.  

Migrate single user

Domain Preparation:
  • Firstly, make sure that you have enough licenses for target Office 365.
  • Secondly, create admin accounts in both source and target Office 365.
  • Now, create a user mailbox, resource mailbox, and distribution groups in the target tenant.
  • Perform ADDS (Active Directory Domain Service) consolidation using the ADDS tool.
  • Now synchronize both the source and target domains. 
Verify Domain:
  • Start the process of verifying the target domain in Office 365.
  • Now add the source domain to the target domain to create the TXT record in DNS.  

(Note: Make sure the domain is using only one tenant. And it will take 72 hours to show the changes). 

Schedule Office 365 to Office 365 migration:
  • Firstly, generate a list of user mailboxes that you want to migrate.
  • Secondly, create a CSV for mapping.
  • Note down the lowest TTL value (Time to Live) on the MX (Mail Exchange) record.
  • At last, disable the synchronization of the source domain. (Disable from Admin center). 
Migrate Office 365 to Office:
  • Stop the mail flow of the source tenant by changing the MX value to an unreachable value. (Enter the lowest value of TTL on the MX record) (Noted in the previous step).
Prepare Source Office 365:
  • Before transferring the mailbox to another Office 365, erase all the objects from the primary domain on the source Office 365.
  • In the window PowerShell, run the below command to remove all the objects from the primary email address.Office 365 to Office 365 Migration-img-1

 

Prepare Target Office 365:

The last step for Office 365 to Office 365 migration. Initiate this step after one hour of performing the last action. 

  • Configure auto-discover CNAME.
  • If you use Active Directory Federation Services (ADFS), configure a new domain in the target Office 365 for ADFS.

Move bulk users

In my opinion, moving mailboxes in bulk (in a hybrid deployment) is most accessible by using the Exchange Admin Center 2013 or Exchange Management Console 2010. However, with some additional preparation, we can use a list of commands for the same task.

In a hybrid server, install Microsoft Online Services and Sign-In Assistant for IT Professionals RTW first. After that, install Azure Active Directory Module for Windows PowerShell (64-bit version) and reboot the hybrid server to complete the installation process.

Next, create a list of mailbox aliases for the users you want to move in bulk. The file must be a CSV file (userlist.csv) containing a header named ‘Alias.’

Connect to Office 365
  1. From the hybrid server, using the ‘Windows Azure Active Directory Module for Windows PowerShell’ console, use the below commands to connect with Office 365.

  2. For the variable ($ONPREMCREDS), use your on-premise credentials (i.e., DOMAINNAME\Administrator). Office 365 to Office 365 Migration-img-10

 

Run the Bulk Office 365 Migration

Now, we’ll use the CSV file we created earlier to perform the bulk migration. Make sure the path on the CSV is local. Use this command to set the variable.

It is the manual method (PowerShell) for free Office 365 migration. Before you use the manual method, let me mentioned some of its drawbacks.   

Drawbacks of the PowerShell

  • Firstly, it is complex and hard to operate for non-technocrats.
  • Secondly, it is lengthy and time-consuming. And users have to repeat the same process again and again.
  • It has a risk of data loss and chances of human error. Manually, a misstep and your Office 365 data can become inaccessible, or you’ll lose it.
  • Manually, there is no guarantee of a successful migration.
  • It doesn’t assure Folder hierarchy and Data integrity.

To eliminate the risk of data loss & drawbacks of the manual method, users prefer professional Office 365 migration tools.
