Hi.

We have a customer wanting to switch from OneNet to Office 365. Because we don't have access to the back end, I was curious how others had done migrations of this nature?

IMAP seems to be an option but it seems to have some fairly unpleasant limitations like max 35MB file sizes etc.

We can just export the PST and Import into Office 365, but that's fairly crude to say the least and with such varying upload speeds, it's not ideal.

Cheers for any information.

BitTitan's MigrationWiz can handle this. The credentials for each user will need to be provided. Full instructions are here.

Have you asked how much they would charge to move it to a O365 tenancy that your customer owns? Or if you can get temporary access to the host for migration? If you have powershell access into the exchange tenancy then you should be fine, but I suspect PSTs will be the most efficient solution if you can't get admin access in. I would hope there is something in the contract to cover this?

I've had success with SkyKick in the past for situations where I couldn't access the host.

Onenet offer a migration service.
Im not sure if you need to purchase 365 from Onenet for this

I would use BitTitan, Have used it in 365 to 365 and Gsuite to 365 migrations and it's well worth the cost.

Why not use the free migration tools that are part of 365?

I've just done a big IMAP migration just using the customer's old email credentials and IMAP server settings.

One mailbox was over 50GB and it completed that without any issues and keeps doing incremental migrations so picks up any new emails that might still go to the old mailbox.

Opinions are my own and not the views of my employer.

Another vote for MigrationWiz. Have used it successfully in many hosted exchange to 365 migrations.
