As announced on Microsoft’s blog, Exchange 2010 is near the end of its lifecycle. In about only 14 months from now, on January 14, 2020, Exchange 2010 will stop being supported. Although the end of the lifecycle does not mean that your Exchange Server 2010 will stop working, it is recommended to start planning the migration to a newer version of Exchange – preferably to Exchange 2019, which has already been officially released in October this year.
Why is it time to leave Exchange 2010?
The main reason is that you will not be able to maintain the server up to date. Once Exchange 2010 reaches the end of its lifecycle, it will no longer get security updates, bug fixes and technical support from Microsoft team. This should sound to you like a good reason to start planning your migration to a newer version of Exchange, preferably to Exchange 2019, which is currently the youngest Exchange edition available.
Why Exchange 2019?
Although Microsoft continues its cloud-only strategy, there are still companies which prefer or need to stay on-premises. The reasons for that are mainly security regulations obligating companies to store business data locally. So if you plan to migrate to a newer version of Exchange, it is worth considering moving to the newest (the youngest) available. Exchange 2019 is at the very beginning of its lifecycle, which is vital from the support and maintenance perspective. And as announced on Microsoft Ignite 2018, this is claimed to be the most reliable Exchange version ever.
Having this in mind, I will show you how to perform the migration to Exchange 2019 using CodeTwo Exchange Migration.
Note: If you look for a way to migrate mailboxes to Office 365, see my other article on migration from Exchange 2010 to Office 365.
Why choose CodeTwo Exchange Migration over native migration path?
Well, you can go with native options when migrating from Exchange 2010 to Exchange 2019. This will require a double-hop migration (Exchange 2010 and Exchange 2019 can’t coexist in the same forest so you need to move to Exchange 2016 first), some time and scripting knowledge. Though it consumes resources like e.g. above-mentioned time, it costs no money. However, as I want to show you the way for fast and painless migration, I will focus on using a third party tool here. Except for simplicity and speed factors, you may want to go with CodeTwo Exchange Migration also for other reasons like:
- Direct migration to Exchange 2019 (no double-hop);
- Option for planning migration ahead, and be sure that your migration tasks will automatically start and stop once proper time comes;
- Zero downtime during mailbox migration;
- Automatic creation of users’ accounts and mailboxes on the target server;
- Auto matching source and target mailboxes.
And the list does not end here. If you want to see more benefits, follow this link.
How to migrate to Exchange 2019 using CodeTwo migration tool?
It may sound a bit “salesy”, but the fact is that the migration with CodeTwo Exchange Migration will save you a lot of time and effort. Below you can find a brief overview of how to set up the software and a migration job.
Note: You can trial the software at no cost for 30 days and migrate up to 10 items per folder. Click here to download the trial version of CodeTwo Exchange Migration. There is also an option to get a temporary license key allowing you to migrate all items from a limited number of mailboxes. To obtain the special key, contact CodeTwo Customer Service.
As I mentioned before, Exchange 2010 and 2019 cannot coexist in one forest. There is no workaround for this infrastructural limitation. Therefore, the guide below shows how to perform a cross-forest migration.
- In the Administration Panel of the program in the Jobs tab, click the New button and then Migration job from Exchange Server.
- Name your migration job.
- Connect the program to the source server via the easy-to-follow connection wizard.
- Once the program connects to the source server, select mailboxes for migration.
- Then, set up the target server connection by following the wizard.
- Match source and target mailboxes. You can do it manually or let the program match mailboxes automatically.
- If you want to run the migration job at a different time e.g. on weekend, you can enable scheduler to activate or stop the job automatically.
- Choose which folders should be migrated.
- Run the migration job and watch how the magic happens.
Once the migration process is finished, you can generate a report which summarizes the migration process. There are available overall, job and mailbox reports. Here is an example of the job report:

I HATE, I say again, HATE that you didn’t mention anything about the necessary cross-domain migration to do this. This article is extremely deceiving. This is a very complicated process no matter how you look at it.
Hello Bob,
Thank you for your input, I didn’t realize the information is not clear. I have updated the article to highlight the need for cross-forest migration, since Exchange 2010 and Exchange 2019 cannot coexistin one forest. I don’t think that any third-party tool will allow to bypass this limitation.
