Summary: Before you start migrating mailboxes from an Exchange Server to Exchange Online, first review best practices, and practices to make sure you get the results you want after you migrate your mailboxes. We can help you choose the best option for your organization to move your mailbox from your on-premises Exchange. There are two ways to migrate your mailbox from Exchange to Exchange Online. If you have fewer mailboxes, you can migrate them to PST and import these PST files into Exchange Online. However, if you have a large volume of mailboxes, the best way is to opt for a third-party utility.
Microsoft officially launched its cloud e-mail, Office 365, in June 2011. Since then, most organizations that previously worked with local e-mail have switched to using it. Moving email to a location is a huge task that requires a lot of knowledge and time. Why did so many organizations decide to take the leap? Is it simply because the cloud is a “new technical savvy” thing, or is there really tangible benefits attached to it?
Why do users need to migrate Exchange On-Premise to Exchange Online?
There are many reasons why organizations choose to create an Exchange in place. The main ones include full control over your hardware and the ability to have complete control over all Exchange data. But since every coin has two sides, then a full local setup means disaster, too, as your important data is at risk. Furthermore, server maintenance costs can be tricky, as well as providing 100% server availability.
The transition to Exchange Online cloud has significant advantages over those offered by On-Premise configuration:
- Exchange Online offers greater scalability without having to spend money on infrastructure. All you need to do is purchase additional email accounts for the new user. The whole process of buying more storage, using additional hardware support, configuring everything, and so on. have been simply removed.
- This saves money because you no longer need to maintain anything. You just invest in your O365 subscription and get all the features that local customization offers, and more.
- Leave everything to professionals (Microsoft), you can be sure of the security of your data. You no longer have to worry about data theft or data loss cases due to catastrophe, technical glitch, etc.
- You don’t have to worry about upgrading to the latest software version. Everything is processed automatically and smoothly: therefore, your users do not experience server downtime or other similar situations.
Common Challenges Faced During Migration
As we have shown, independent email migration is very risky and requires expert supervision and care to be successful. Many things can go wrong, so try to do them only when you are sure what and how to do them. If not, you may face one of the following issues:
- Stability Issues in Exchange Server Environment
- Server Downtime during the migration process
- Slow Network Connection can result in more time consumption
