When migrating multiple PST files to Microsoft 365, I would recommend planning the process before starting the actual import. A little preparation can make a significant difference, especially when several users and large email archives are involved.
First, create a backup of the original PST files and organize them according to the users or departments they belong to. Check the files for accessibility and make a list of the destination Microsoft 365 mailboxes. This will help you avoid confusion when assigning PST files to their respective accounts.
Next, decide whether Microsoft's built-in import method meets your requirements or whether a dedicated migration tool would be more convenient. The native method can be suitable for organizations comfortable with Microsoft's import workflow. However, when working with multiple files, a specialized tool may provide a more straightforward way to manage the migration.
One option worth exploring is Kernel Import PST to Office 365. It offers features intended to simplify PST migration, particularly when administrators need to process multiple files or manage data across several Microsoft 365 mailboxes.
Some useful capabilities include:
Bulk PST migration: Import multiple PST files rather than handling every file as a separate manual task.
Mailbox mapping: Assign PST data to the appropriate destination mailboxes.
Selective migration: Choose the required mailbox data instead of importing everything unnecessarily.
Incremental migration: Help avoid reimporting items that have already been migrated, depending on the migration workflow.
Migration reports: Review the migration process and check the results after completion.

Regardless of the method you choose, I would suggest testing a small batch of PST files first. Verify that the emails and attachments are accessible, the destination mailboxes are correct, and the folder organization meets your expectations. Also, confirm that the required Microsoft 365 permissions are configured before beginning a larger migration.
Finally, keep the original PST files until you have reviewed the imported data and confirmed that everything important is available in the destination mailboxes.
