Just like above-mentioned scenario, there come situations when some companies acquire other companies to increase their productivity and grades. When this comes about, the acquired company’s IT infrastructure usually gets merged with the parent organization. The opposite of this condition is also true. There also comes such situations when a company sales off one of its acquired and unwanted business at a low price to encourage someone to buy it or because of divisions. Thus, the child company, which is being sold off must have its all IT infrastructure separated from the parent company. In such scenarios, users want to migrate their data from one Office 365 domain to another domain’s account, migrate users and mailboxes from one domain to another, or domain to domain migration.

Merging and acquisitions of organizations are some conditions in which separate cloud IT infrastructure required to be unified or joined, if possible. In this technical paper, we have discussed one such operation i.e, Office 365 to Office 365 migration. As Microsoft does not offer any functionality to transfer mailboxes between two Office 365 tenants thus, we have come up with an automated solution. Discussed third-party solution is completely safe and secure also, does not requires so much technical expertise to execute the data migration.
