Hi Aditya,
Can you know the exact requirement
Is there only 10 users in the forest abc.com
What is the pilot users ? Are there more users apart from these 10
If its only 10 users the simplest solution would be just export mailboxes from abc create new mailboxes for them and import it on the new mailbox
If you are have more number of users then cross forest migration is the best solution
Probably you would need to share a name space if these 2 forests are very large and if the migration takes time
refer this post for understanding cross forest migration
Hi,
As Sathish mentioned, export-mailbox and import-mailbox only handle the data with .pst file, and this command cant be used for public folder.
More details about Mailbox Import and Export Requests, for your reference:

If you want to remain the relationship of user and group, please run cross forest migration:
1. Create forest trust.
2. Prepare required attribute for cross forest mailbox moving, then run ADMT to sync attribute.
3. Run New-MoveRequest to complete moving.
More details please refer to the link as Sathish mentioned.
Thanks
