In this article, our experts from DPC Technology have unraveled the complexities of email migrations. The article also consists of a guide highlighting the features of BitTitan as a robust email migration tool. Whether you're a tech enthusiast, a business owner looking for email migration, or just curious about the process, scroll down the blog to the end to answer your questions.
How Does Email Flow Work For The New Tenant?
Wondering how email addresses work for new tenants and what is the entire process. Before understanding the process, let's delve into a common concern.
Can I keep my old email address?
One of the most common concerns while email migration is whether you can keep your old email address. Let's try to understand how email flow and migration works by drawing an analogy with a cell phone. And it will answer all your related questions. Just think, who would prefer to buy or upgrade to a new cell phone if you have to change or replace your existing phone number? In simple words, the answer to the above question is yes; you can certainly keep your old email address.
MX Records: Core Mechanics of Email Flows
For email flows, think about the outside world reaching you at your domain. The core mechanics lie in the DNS records, specifically MX records. These records act as a guide for the email flows to the right tenant. All you need is a cautious approach to handling MX records with care to avoid disruptions during the migration and reach the accurate mailbox. The timing plays a vital role in the seamless transition. Premature updates can lead to unintended consequences and pitfalls. And once the MX records are updated, the functions start rerouting them to the new tenants. Additionally, the existing email doesn't need to cease to function as soon as the new tenant activates. Thus, it is advised to inform users about migration to prevent unintentional retention of the old tenant.
5 Phases of Email Tenant Migration
To make things simpler and more understandable for you, our experts have explained the entire process of intricating email migrations in five simple phases.
Phase 1: Acquiring Essential Information
The first phase involves acquiring the essential information. It includes access to DNS for the domain name and existing email tenant. However, since obtaining information from end-users can be challenging, our experts advise using Excel sheets as the central hub of the data. To minimize human errors, avoid manual entry and export all the emails securely via an Excel sheet. The sheet will serve two purposes. First, it will store the emails, and second, it also serves as a template for creating accounts, managing migration projects, sending mass emails, and setting up aliases. Thus, it enhances efficiency and accuracy.
Phase 2: Review and Verification
Once you have exported the information related to the domain and existing old tenants, it's time to verify that again. At this phase, you can also take the opportunity to convert irregular email accounts into shared mailboxes and align them according to the client's preferences. You can collaborate either with the client or end-users to confirm the account for migration. Both parties, the client and service providers, should be fully aware of and agree to the plan.
Phase 3: Setting Up the Initial Migration Process
Once you have accessed the data in the Excel sheet and reverified the plan, you can proceed with creating new tenants following the required steps. For instance, let's take a look at the process of migrating to an O365 destination tenant.
- Initial text record: The O365 migration process is initiated by adding a domain name and proving ownership through a text record in DNS.
- Verifying credentials: Before proceeding with licensing, verify credentials and ensure read and write access between accounts.
- Resetting passwords: In the scenes where access to account credentials is challenging, you might be asked to reset the passwords. This will ensure a streamlined process and identify unresponsive users.
- Transparent communication with the clients: It takes transparent communication with the users for a successful tenant migration. Notify the clients about upcoming migration, seek necessary information, and obtain approvals for a smoother transition.
- Data backfilling: Especially in larger migrations, it is essential to backfill the data up to 30 days ago to mitigate potential throttling issues.
Phase 4: Final Cut-Over Planning and Migration
The fourth phase involves scheduling a final cut-over date with the clients and end users. Communicate with them clearly and concisely regarding access and functionality during and after the migration. You can practice smoother communication by sending mass emails describing the instructions about accessing and utilizing the new email platform. Finalize the migration process by securely distributing the final credentials a day before the final cut-over. Once the final cut-over planning is done, the accounts are ready to be added to the new tenant using the PowerShell script.
Phase 5: Post Migration Support
The last phase reflects on post-migration support. Here again, the crucial element is communication. Describe the clients about the post-migration consequences and expectations, including potential delays in setting up local Outlook configurations. Reassure the end users about available expert assistance and dedicated support throughout the transition. Not only the assurance, but you also need to emphasize the commitment to assisting and ensuring a seamless experience for the users to adapt to the new email environment.
How To Employ Automation Using PowerShell Scripting?
As adding user accounts to the Microsoft 365 tenant based on the information stored in the Excel sheet is a hassle process, automation is the key. Powershell Scripting is a powerful tool for Microsoft Graph API to connect to a Microsoft 365 tenant and automate user creation based on data from an Excel sheet. You can also utilize the PowerShell console directly, but writing a script using PowerShell helps ensure that all steps are covered and reduces the chance of errors. Here are a few steps and features of PowerShell scripting.
- Microsoft Graph Module: It is an essential module that needs to be installed and imported into the PowerShell script. The module facilitates interactions with Microsoft 365 services through the Microsoft Graph API.
- The Connect-Graph cmdlet: The Connect-Graph cmdlet is used to establish a connection to a Microsoft 365 tenant. It prompts the user to enter administrator credentials for the tenant.
- Import-Csv cmdlet: This cmdlet assists in loading data from an Excel sheet into a variable called new users. This sheet likely contains user information such as user principal names, passwords, etc.
- For Loop Iteration: The for loop is used to iterate through each user in the new user's array. The loop appears to handle processing user information for each iteration.
- New-Imac User Cmdlet: The cmdlet is used to create a new user in the Microsoft 365 tenant. Various attributes, such as display name, password, email, nickname, given name, surname, etc., are provided as parameters to the cmdlet.
What are the cautions to be kept in mind while employing PowerShell scripting for email tenant migration?
The script utilizes variable referencing, which assists in matching variable names with column headers in the Excel sheet to avoid errors. Additionally, the script includes a section for licensing users after their creation. That establishes a firm identification, but you need to be cautious while licensing, especially if you only want to assign specific licenses to certain users. The script requires the Excel sheet to be in a .csv format for compatibility with PowerShell. Thus, our experts advise using CSP (Carbon Copy) as a throwaway version for modifications and maintaining the original Excel document as a working copy.
After user creation and licensing, verify the results in Microsoft 365 to ensure accounts are created and licensed as intended.
