Q- Can I connect mailboxes from two different IMAP servers?
Q- Will the attachment migrate along with the emails?
I have a customer who has about 50 email accounts, or about 1.2Tb of data on the GoDaddy Microsoft 365 platform. There are several limitations we are running into and the customer would like to migrate to a true Microsoft 365 Platform.
I have done a M365 Tenant to Tenant migration before and it was not a pleasant experience. Microsoft provided 0 support, and actually told me that it was impossible to do, so I basically had to perform complete backups of all email accounts, then re-upload them.
I do have some concerns about the migration because I basically have to release the tenant name back to public, then re-acquire it after 24 hours, according to what I have seen. The customer has someone (believed to be their previous IT person who may or may not still be in contact with employees at the company) actively trying to sabotage them on a very frequent basis. I am concerned this person may try to acquire the tenant's name during the 24 hours and get it before I am able to.
Beyond that, I am very interested to know what tools you have successfully, or unsuccessfully, used for this process. While I have a fairly fast 500Mbps internet connection, it still seems to take several days to download the entire data set. I would like something I can do a trial run with, then something I can run differential backups with right up until the last minute.
I would also like to set up something to cache all the emails while the system is down. I am thinking something along the lines of a Linux mail server, or maybe a 30-day trial of a mail security program that has that functionality.
Hi @eg1995 ,
To migrate from godaddy to o365, you could follow these steps:
1.Purchase an Office 365 plan from Microsoft directly.
2.Create mailboxes on the new subscription using the default onmicrosoft.com temporarily.
3.Perform an IMAP migration to move the mailbox data.
4.After the migration, remove your custom domain from your Office 365 plan in GoDaddy.
5.Cancel your Office 365 subscription in GoDaddy.
If you are not clear about above actions in GoDaddy, you may need to consult GoDaddy support for the detailed steps.
6.Add and verify your domain in Office 365.
7.Change the user mailboxes from onmicrosoft.com to the verified domain.

I have extensive experience with tenant-to-tenant migration projects. In my most recent project, I managed the migration of workloads from GoDaddy (Office 365) to standard Office 365.
The primary difference between GoDaddy Office 365 and standard Office 365 is the login page, which is customized by GoDaddy. Apart from that, the migration process is essentially an Office 365 to Office 365 migration, which is straightforward when using third-party migration tools like AvePoint and BitTitan (my preferred tool).
These tools are particularly effective for migrating diverse workloads, including Teams chats, Teams Channels, SharePoint sites, OneDrive, and Exchange mailboxes. It's important to note that IMAP migrations only transfer emails and do not include calendars, signatures, contacts, and other data, making third-party migration tools necessary for comprehensive migrations.
