Migrate public folders to Office 365
Important: To perform migration of public folders, you need to have 25 licenses of CodeTwo Office 365 Migration. The program always uses 25 licenses, no matter how many public folders you want to migrate. Additionally, be sure to create public folders on the target server prior to migration – see this KB article for instruction.
To migrate the content of public folders from Exchange to Office 365, you need to create a migration job. Follow the steps below to set it up:
Create a migration job
- Go to the Jobs tab, click New and select Migration job from Exchange Server…. This way you open a new job creator.
- In the Job name section, provide your job name. Click Next.
- Then, you need to select public folders in the Migrate mailboxes fulfilling the following conditions section.
Note: By default, there are All users and Public Folders selected. As we want to set up this job exclusively for public folders, All users selection needs to be removed. To remove it, select it and click Remove. Then, click Next.
- In the Target mailboxes section, the connection should be already configured (we covered this in the Configure source and target server connections section above). Click Next.
Match source public folders with the target ones
- The next step is to match source public folders with the target ones. In the Match mailboxes section, click the Match mailboxes button.
- In the resulting window, click on Click to match target and Choose an existing user…
- In the Match target user/mailbox window, find your public folders mailbox, select it and click OK.
- In the Match mailboxes window, you should now see public folders matched.
- Click Save in the top left corner of the window to save changes. Close the window. Then, go back to the initial Match mailbox window. Click Next.
- In the Scheduler section, you can set up activity time for the migration job. In my example, I leave it untouched as I will run the job manually.
- Next step is to specify Time filter. By default the Migrate all items regardless of their age option is checked. If you do not want to change anything here, click Next.
- In the Folder filter section, specify folder types you want to migrate. Click Next.
- In the Address rewrite section, leave the checkbox ticked unless you are sure you do not want to change EX to SMPT addresses. Click Next.
- In the Concurrency section, you do not need to change anything. Click Next.
- The final step is Job summary where you can overview your settings. Once everything is set up correctly, click Finish.
Start migration of public folders
- Now go to the Jobs tab in the administration panel. There you should find your migration job. Click Start to run it.
- Once the migration job is running, you can monitor the process directly in the program’s panel (in the sections: Job migration progress, Job good news, Job bad news, you will see statistics and alerts from the migration process). After migration is finished, you can also generate overall, job or mailbox reports that illustrate the migration results.
