We are primarily using Office 365 Business Premium. One of our users has a very large (around 108 GB) in-place archive and would like to migrate that (just the archive, not the entire mailbox) to a G Suite mailbox.
I can create a PST using Outlook, but I've read that PST files have some sort of a 50 GB limit.
Any other options? I just need a way to extract the in-place archive to something that can be imported into G Suite.
