I'm working on a migration for a SMB customer (~25 mailboxes) from on-premises Exchange 2010 to Exchange Online; I've set up the hybrid configuration, and I'm currently moving the mailbox data; everything is working fine.
The source environment has a single public folder, which hosts several hundred contacts; its total size is quite small, and the customer thinks a one-shot migration of those data (which don't change often) is perfectly fine. The public folder is not mail-enabled, and the permissions are as simple as "everyone can read it, a couple users can edit the contacts".
I'm familiar with the official public migration procedure for public folders, but I find it to be quite cumberstome for this situation, where very little data needs to be moved and no continuous sync is required.
Is there any simpler way to achieve this? Ideally, I'd be looking for something like "create an empty public folder structure on Exchange Online, export current public folder data to a .PST file using Outlook, connect Outlook to Exchange Online, import data".
