How many projects should I create?

You should avoid creating one Project per item. Even for a large project (thousands of items), you would normally use only a few Projects. Our system will detect the creation of too many Projects.

For smaller migration Projects, we recommend creating one Project per Source and Destination system.

Once you have a Project configured, you can add a list of items under that Project. You can add items manually, by uploading a CSV file, or by using Autodiscover.

In some situations, you may want to create more than one Project per Source and Destination system.

You want to categorize items. Items sometimes represent user groups. You could create Projects for "pilot users," "VIP users," ​etc.
You want to stage your migration. Items will advance from one stage to the next. You could create Projects for "Phase 1", "Phase 2", etc.
If you have a large number of items in your project. For example, if you had over 500 mailboxes in your Project, it would be advisable to split these items up into more than one Project to improve manageability.

Refer to our instructions regarding Moving Items from one Project to another. All statistics, as well as the ability to resubmit using mailbox migration licenses, are preserved.
