Access historical data after Azure AD tenant changed

[Deleted user]

One of our customers (ABC.com) is using Azure AD SSO to access Atlassian JIRA. The company underwent a merger and acquisition recently and taken over by another company (ABC.com). As a result of the merger, all users in ABC.com will be recreated in XYZ.com's Azure AD with the same email address (user@abc.com). The question I have is once we have moved/recreated the ABC users from one Azure AD tenant to the other, will they be able to access their historical data when they sign in from the new Azure AD tenant. Please note that they will use the same email address.

Cheers,

Harish

Hi @[deleted],

thanks, you gave me a crucial set in the last update - this is referring to Cloud. Unfortunately there I haven't got a answer for you.

Unless someone else has had this scenario before on cloud, this may actually be a fair Question to raise a support case with Atlassian.

Cheers,

Hi Harish,

that may depend a little bit how they implemented SSO - on the Server variants you usually need a 3rd Party Plugin (like ours). With our plugin for example this would work by switching out the IdP.

So if you share a bit more information, that would help us to give you a better answer.

Cheers,

Hi Christian,

Thanks a lot for the response and sharing the plugin details. Currently the customer (user@abc.com) is using SSO via Azure AD to access Atlassian cloud. The steps involved for setting up SSO is listed in this article - https://docs.microsoft.com/en-us/azure/active-directory/saas-apps/atlassian-cloud-tutorial 

As a result of the merger, we will be creating user accounts of company A in company B's Azure AD with the same old email address. What changes though is the Azure AD tenant used for authentication via SSO. I would appreciate if you can let me know if the Company A users will have access to historical data once the tenant is changed.
