Domain migration question

Occasional Contributor
Due to an recent acquisition, the company that I work for (Company A) needs to migrate another company's tenant (Company B) into ours.

 

Company B is running Azure AD + M365, including several other services such as Azure DevOps. 

 

Now to my question:

Let's assume that once we have successfully migrated all data residing in Azure AD and M365, set up the domain, migrated all mail, aliases and set up the necessary DNS-records and such....should we be expecting any problems (such as authentication, sync etc) once the companyB-users will try to log into Azure DevOps with their old login credentials?

 

If so, how do we prevent this from happening? Any feedback is greatly appreciated, thanks!

If cx follows the proper instructions provided by MSFT he won't be facing any issues.
 
As per this article, below are the pre-requisites:
 
  • You're in the Project Collection Administrator group for the organization.
  • You're a member or a guest in the source Azure AD and a member in the destination Azure AD. For more information, see how to convert an Azure AD guest into member.
  • You have 100 or fewer users in your organization. If your organization has more than 100 users, contact support for help with changing your Azure AD.

Do the following task:

  • Request that SSH keys be manually cleared by Support.
 
BTW, there are many migration tools available in VS Marketplace which can automatically generate access tokens, rename/adjust the accounts with VS subscriptions in destination tenant.
