Office 365 EA to CSP

[Timil]

Hello

I have a customer that currently have an EA with a reseller in another country, but want to migrate from them to our CSP.

They only have Office 365 ressources.

All I can find is documentation about migrating an Azure EA to an Azure CSP, but no documentation about Office 365.

Can I just send them the business invite link to make us the new manager of their Tenant? Or is there a full migration to be handled, including the painfull migration of the O365 datas to a new tenant?

Thanks

Hi @Timil ,

There was a similar thread recently on the topic : https://www.microsoftpartnercommunity.com/t5/Microsoft-Partner-Network/Microsoft-EA-to-CSP/td-p/5839.

According to it, for O365 there should be no actual technical move, only assigning the licenses to the customer. @JanoschUlmer , could you kindly confirm this, please ? 

Hope this helps,

Andra

Can confirm - just send them the reseller invitation (noticed you mentioned "in a different country" - reseller invitation can only be accepted when in same CSP sales region as per https://docs.microsoft.com/en-us/partner-center/regional-authorization-overview) and then you are able to provision licenses to them and no need for technical migration to new tenant.

However, if tenant locatuion is not in your sales region, you woul dneed to create a new tenant and then also migrate data & users to the new tenant.

For the secanrio that you are in the same sales region - In order to switch the billing to CSP you just need to provision new licenses via CSP - when the EA licenses are then expiring the licenses will be automatically reassigned. If the licenses from the old contract expire before you provision new ones via CSP, you will need to reassign licenses (no data loss if reassignment happenss within 90 days).

Thanks for the help.

Hi Janosch,

Please I'd like to know the steps taken to migrate already existing users and data to the new tenant. (Assuming Customer and Partner Reseller are in different countries/regions).

I'd appreciate if you could also refer me to a link.

Thanks.

@Cheezee :

This is agood starting point: https://docs.microsoft.com/en-us/exchange/mailbox-migration/migrate-mailboxes-across-tenants

As noted in the article Microsoft doe snot offer a migration tool that can move data, so likely a third party migration tool needs to be used. 

Of course you can also "manually" copy data - e.g. moving sharepoint data to local devices, and then sync up again using OneDrive sync client - or use Outlook PST files to migrate mailbox content. Depends on how large the customer is and what data exactly needs to be moved - in most scenarios a 3rd party tool that can directly move data, configuration and permissions is preferred.
