Exchange Hybrid test plan checklist

What to do after installing the Hybrid Configuration Wizard (HCW)? After installing HCW, the on-premises Exchange environment is configured with Office 365. Is there an Exchange Hybrid test plan checklist, or can we start migrating the on-premises items to Office 365? I recommend using a checklist before migrating the mailboxes. You will create test items step by step in both environments and test thoroughly. In this article, we will have a look at the Exchange Hybrid test plan checklist.

I recommend to install a separate Exchange Server 2016 and install HCW on it. Then you can keep the Exchange Server 2016 running and decommission the other Exchange Servers.

Before you start the migration to Office 365 from your Exchange on-premises environment, what’s better than making sure that everything is working? That’s why I recommend going through the Exchange Hybrid test plan checklist document. Create the test items, as shown in the below document one by one. After creating them, test if it’s working. If it’s not working, troubleshoot and fix the issues. You can download the document from here.

Planning and testing are essential. You don’t want to see that users can’t connect to shared mailboxes. Or that they can’t look into the calendar of their colleagues. More issues can go down the road once you start migrating without testing first.

I hope that the checklist document will help you to create an easy migration to Office 365.
