Migration of data from tenant to tenant is not as easy as it seems – it might show up along this way in light of the fact that Microsoft possesses both the parts of what you need to move your information between, be that as it may, this isn’t the situation at all. What’s fascinating is, it varies significantly by office 365 workloads.
There might be a time when there is a need to migrate your mailbox through office 365 to office 365 migration. People might not be able to find a proper way to migrate Office365. Following a manual approach might become hectic and complicated, as they need a great deal of technical knowledge and expertise, besides, you might not be able to get the proper guidance of the queries you may face. On the other way, it is always better to approach a third party, or in other words, office 365 tenant to tenant migration tool, for bringing about the tenant to tenant migration.
Here we would write some basic information about migrating from office 365 to 365 (from one tenant to another). This brief discussion would help you somehow, but for the proper guidance, one should see tenant to tenant migration guide.
The following steps are helpful to you before you prepare your office 365 for the tenant to tenant migration.
1. Preparation of the Domain
Make sure you already have enough licenses. For bringing about smooth migration, there must be created an admin account in the source as well as the target account. Following that, in the target o365, create mailboxes (user and resource), and distribution groups. You can synchronize the source domain with the target domain (if necessary) – this is performed by a tool or by manual means.
2. Verification of the Domain
For starting a verification of office 365 target tenant domain, in the admin center of the target office 365, make TXT records in DNS. You should be certain that there should be only one user for the domain. Else, it can fail your verification. It is a time taking process, which can take about 72 hours.
3. Set the Migration Schedule
User mailboxes that you should migrate, create their list, and generate a CSV file for mapping. Now, from the primary email domain, note the least value of TTL on the MX record. Meanwhile, directory sync is to be disabled from the source tenant.
4. Finally, the Migration Stage
- The inbound mail flow should be stopped. This can be done by the third-party service or manually by making amendments in the MS record to the value, which is unreachable. You can plan the schedule with the help of TTL value, which you noted in the previous steps.
- The primary mail domain – is supposed to be removed from all source tenant objects, before its shift.
- The target domain – prepare it by verifying the source tenant. Ideally, it should be done following one hour from the previous step.
The next step involves account passwords and licensing.
Finally, here is the time to choose the migration method. Your decision depends upon the size of the data. You can accomplish migration through PowerShell scripts. Office365 tenant to tenant migration tools, like on-demand migration, are highly recommended for the purpose – comparatively, it works better!
