How to Migrate Office 365 Tenant to Another Tenant Without Tool?

While there are Tenant-to-tenant Migration tools available, PowerShell scripts can offer a powerful and flexible solution that allows for fine-grained control over the migration process. In this section, we will explore the steps involved in migrating email data from one Office 365 tenant to tenant using PowerShell scripts, as well as best practices for ensuring a smooth and successful migration.

1. Connect to both Office 365 tenants:
Before starting the migration, connect to both the source and destination tenants using PowerShell. To do this, follow these steps:

a. Install the Azure AD and Exchange Online modules:

Install-Module AzureAD
Install-Module ExchangeOnlineManagement

b. Connect to the source tenant using the Connect-AzureAD and Connect-ExchangeOnline cmdlets:

Connect-AzureAD
Connect-ExchangeOnline -UserPrincipalName <adminUPN>

c. Connect to the destination tenant using the same cmdlets:

Connect-AzureAD
Connect-ExchangeOnline -UserPrincipalName <adminUPN>

2. Export mailboxes from the source tenant:

Use the New-ComplianceSearch and New-ComplianceSearchAction cmdlets to export the mailboxes from the source tenant. This involves creating a compliance search to find the mailbox data and then exporting it to a Outlook data file.

a. Create a new compliance search:


New-ComplianceSearch -Name <searchName> -ExchangeLocation all -ContentMatchQuery <query> -StartDate <startDate> -EndDate <endDate>

b. Start the compliance search:

Start-ComplianceSearch -Identity <searchName>

c. Export the search results to a .pst file:

New-ComplianceSearchAction -SearchName <searchName> -Export -ExportFilePath <filePath>

3. Import mailboxes to the destination tenant:

Use the New-MailboxImportRequest cmdlet to import the mailboxes into the destination tenant. This involves creating a target mailbox and then importing the .pst file into it.

a. Create a new target mailbox:

New-Mailbox -Name <name> -Alias <alias> -UserPrincipalName <UPN> -Password (ConvertTo-SecureString <password> -AsPlainText -Force) -DisplayName <displayName> -FirstName <firstName> -LastName <lastName> -ResetPasswordOnNextLogon $false -PasswordNeverExpires $true -PrimarySmtpAddress <emailAddress>

b. Create a new mailbox import request:

New-MailboxImportRequest -Name <requestName> -Mailbox <mailboxName> -FilePath <filePath> -TargetRootFolder <folderName> -IsArchive

c. Start the mailbox import request:

Start-MailboxImportRequest -Identity <requestName>

4. Verify the migration:

Once the migration is complete, verify that all data has been migrated correctly. This involves checking the mailbox size, verifying that all emails are present, and testing the mailbox functionality.

a. Check the mailbox size:

Get-MailboxStatistics -Identity <mailboxName> | Select-Object TotalItemSize

b. Verify that all emails are present:

Search-Mailbox <mailboxName> -SearchQuery <query>

c. Test the mailbox functionality:

Log in to the target mailbox and verify that all emails, contacts, and calendar entries are present and functioning correctly.
