Migration is not just about moving your data, it also includes accuracy in handling large mailboxes, attachments and folder structure. This guide focuses on all these terms, so follow the proven methods properly to prevent confusion and ensure a smooth migration. Let’s dive into the article.

Why Migrate Zimbra to Exchange?

Zimbra is also a versatile email platform but many users gain interest in Microsoft Exchange as it offers an advanced email environment. This is why organizations look to migrate from Zimbra to Exchange.

Here, we have listed some of the major reasons:

• Migrating Zimbra to Exchange allows users to work seamlessly with Microsoft tools like Teams, OneDrive and SharePoint. This helps to improve teamwork and communication across the organization.
• Microsoft Exchange provides strong security features which includes email encryption, data loss prevention (DLP), and anti-phishing protection tools.
• Exchange handles large mailboxes efficiently because it supports fast performance that helps in maintaining data growth.
• Zimbra often faces sync issues with mobile devices whereas Exchange offers advanced cross-device synchronization or real-time email sync with all devices.

How to Migrate From Zimbra to Exchange? Manual Method

Manual methods are cost-effective and typically done via IMAP setup. In this section, we have listed expert tested manual ways. Follow them carefully.

Step 1- Configure Both Accounts in Outlook

1. Open Outlook and navigate to File > Add Account.
2. Enter your Zimbra email address and click Connect.
3. Then, choose IMAP and enter incoming and outgoing mail server settings.
4. Lastly, verify with OAuth and wait for Outlook to sync your mailbox.

Similarly, repeat the same step to add Exchange account in Microsoft Outlook. When configuring an Exchange account, choose Exchange from the Advanced setup.

Step 2- Move Your Data

1. Select emails in the Zimbra folder.
2. Once done, drag and drop them in the corresponding Exchange folder.
3. Alternatively, right click and choose Move > Copy to folder.

Note: Always use Copy instead of Move so that your original emails remain on Zimbra server as a backup, if in case connection is lost or the sync process fails.

Limitations of the Manual Method

• A stable internet connection is required. Any interruption can lead to data loss.
• Dragging emails can result in an unorganized management of emails.
• A complex configuration setup for non-technical users.
• IMAP credentials should be correct otherwise it will show an error.

On 1st July 2025, Microsoft announced that the much-awaited Exchange Subscription Edition (SE) is now in the General Availability stage. So IT administrators can upgrade their soon-to-expire Exchange 2019 servers to this new version and get used to what Microsoft calls the future of on-premises email management.

This new RTM release represents a major turning point. Especially for those organizations that have never used a subscription-based model before. Every version of Exchange that came before this one was a triennial one-time procurement system.

Don’t worry, you are not alone. We are here with this guide to break down everything you need to know about the change.

We will explain to you what the new licensing rules are and give you a step-by-step walkthrough of the upgrade process. Before we deploy the new version, let us study what the term General Availability means in the context of Exchange Server SE and why Microsoft released it in RTM.

What Does “Exchange Subscription Edition (SE) is Now in General Availability” Mean?

This announcement means that the Exchange Server Subscription Edition SE (the successor to Exchange Server 2019) can now be downloaded from official sources.

Like many of its other products already Microsoft has now brought the on-premise Exchange Server into the Modern Lifecycle Policy.

This means, now the support for Exchange SE will be available perpetually to all the clients as long as they choose to remain subscribed.

and continue from there.

Steps to Install the Exchange Subscription Edition (SE)

You must decommission and remove any instances of Exchange Server 2013 if they still remain.

Before you install Exchange SE RTM, make sure that you update Exchange Server CU 14 or CU 15 if you operate an older edition of the 2019 version. Upgrade from Exchange 2016 to the latest Exchange Server 2019 CU 14 or CU 15 edition.

Step 1. Run Pre-Flight Checks: Take full, verified backups. Run the official Exchange HealthChecker.ps1 script to ensure your server is healthy before you start.

Step 2. Enter Maintenance Mode: Use the standard PowerShell cmdlets to safely put the server into maintenance.

Step 3. Run the Upgrade: Mount the downloaded ISO file. You can either run Setup.exe from the graphical interface or use the command line. Both methods work perfectly.

Step 4. Reboot the Server: A reboot is required after the installation completes.

Step 5. Validate the Upgrade: After the reboot, run HealthChecker.ps1 again. This is a vital step to catch and fix any configuration changes. Also, check the build number in the Exchange Management Shell to confirm the new version.

Step 6. Exit Maintenance Mode: Once you’ve confirmed the server is healthy, take it out of maintenance mode and test all services.

Understand the Exchange Subscription Edition (SE) Pricing Structure

This table provides illustrative cost estimates for businesses upgrading to or maintaining Exchange Server Subscription Edition, compared to the Microsoft 365 cloud alternative.

Note on Price Increases: These estimates are based on the recent price hikes. Server Licenses increased by ~10% on July 1, 2025, while Core & Enterprise CAL Suites increased by 15-20% on August 1, 2025.

Conclusion

The Exchange Server Subscription Edition SE marks a new era for on-premises email. The shift to a subscription model and a continuous update cycle is here to stay. While it requires an adjustment in mindset from “buy once” to “stay current,” it provides a secure and sustainable path for the future. With a clear upgrade process and a more generous migration timeline, the journey to the next generation of Exchange Server is less daunting than it might appear.
