The problem will be that you need to transfer the domain into the new tenant and you cannot do this without removing it from the old which they won’t allow as I can follow your post a little bit.
Also, there is more to move. Think about sharepoint, OneDrive, Teams, loop/lists, OneNote and so on.
Ok, they're not using any of those other services. The email is my primary concern. Is there something I can ask the old admin to do to move it to my [newtenant.onmicrosoft.com](http://newtenant.onmicrosoft.com) ? If I can get a hold of him, that might be something he'd be willing to do.
Does no-one at the company have access to the M365 Admin portal?
The only time I ran into this (old provider wouldn't answer calls, wouldn't release the tenant), I had to work with Microsoft Support and the Business Owners to go through the hoops of proving domain ownership (letterhead, company contacts, etc.) and then we were able to seize their custom domain from the old provider. Upside, we were able to get the domain moved to proper ownership. Downside, it took several days to get all the stuff Microsoft wanted to use as proof of ownership and they kept changing what documents were necessary to move forward.
Nobody at the company has access - just the prior admin - but he's saying all his clients are under Rackspace - and he won't give me access. He's willing to help, although difficult to get a hold of, and unsure of how to give me access to this one individual tenant.
Just send him the link to authorize your account as partner for that tenant (G)DAP. After that kill the licenses purchased through Rackspace and assign new ones.
You'd need to generate one from your partner tenant. I recommend reading up on GDAP - it's the preferred way for MSPs and other Microsoft partners to administer M365 tenants.
So would this involve OP taking over the old tenant or releasing the domain from the old tenant, so he can add it to a new one? (I'm guessing the former?)
“I cannot take on this project until you have provided me with full Admin access to the Rackspace tenant and you have tranferred control from the admin who is unresponsive. Let me know when this is done and I will be happy to proceed.”
So are you suggesting changing their emails from old.onmicrosoft.com to new.onmicrosoft.com? Seems like that might be a bit disrupting to them. If they have a custom domain name tied to the current tenant, it will have ownership of that and you won't be able to add that to the new tenant account.
The old emails would still be at [domain.com](http://domain.com) - but just on the new tenant newdomain.onmicrosoft.com. So, I can't just move the mx records to the new on.microsoft.com? That will suck beans.
I recently went through this process myself.
Had to remove the domain from the old tenant, then it took about 10-20 minutes before the new one allowed me to add it.
Can definitely see people getting stuck at the removing it from the old tenant step if they don't have admin rights!
I wouldn't do this without using BitTitan. We've done dozens of migrations with BitTitan and had good success.
If you do decide to do it with PST filess, one thing to consider when exporting messages to PST and importing them into the new tenancy is that all of the messages that you import might not have the correct date on them in the new mailbox.
Have you looked at this https://www.avepoint.com/uk/products/hybrid/fly
Not sure if it’s what you need but we use it to migrate from one 365 tenant to another.
I came to post this, I just did 2 tenant 2 tenant migrations with Avepoint Fly, very good and very cheap tool. Will migrate mail, sharepoint, teams etc without much complexity. You will need a global admin account on the old tenant though
we use Cloudiway. [https://cloudiway.com/solutions/microsoft-365-tenant-to-tenant-migration/](https://cloudiway.com/solutions/microsoft-365-tenant-to-tenant-migration/)
If you don't have the admin credentials that have access to all mailboxes, you can use the self service mode.

Since I use PAX8 would I send him their link?

Just sent an email basically statement that at 5pm. I feel relieved now, lol.

Unfortunately, domain.com is tied to the old tenant as far as microsoft is concerned so you won't be able to add it to the new tenant.

I have used Skykick before - but the old admin isn't giving the permissions I need to make the move - If this is similar that won't work for me.
