Teams migration is pretty complex as compared to migrate SharePoint 2010 to SharePoint Online or Azure migration as unlike these tools, all the Teams data cannot be sorted group-wise at specific locations. Rather, they are sorted by the nature of the content. Hence, manual migration will include pulling up every different location and allotting them to the dedicated Teams. A task that seems challenging and is much more challenging when we try to perform it.
For Microsoft Teams Tenant to Tenant Migration, it will be very challenging to perform the process manually as it may include collecting data from the following sources:
SharePoint Team site
SharePoint Teams sites save all the data and folders saved in the teams shared in channels or document library. It also involves the Teams wiki page, external emails, and assets of OneNote from Teams channels.
Exchange Team mailbox
This location includes the Teams group chat mails, channel chat conversation history, contacts, and emails.
Exchange mailboxes of specific users
Every individual mailbox will hold private one-to-one chats with that specific user besides the voicemails and conversation history. It also includes the calendar meeting details.
OneDrive for Business of private users
Each one drive user account is linked to Teams and all the attachments transferred in private chats, call messages, or meeting chats windows are uploaded and saved in the particular OneDrive user account.
OneDrive organizational document library
Users’ OneNote files along with all the details are stored here.
Images, videos, and all other types of attachments except GIFs that have been transferred in chats are saved in the Azure account.
All the recorded meetings are saved in Microsoft Teams for any further references.
Third-party storage provider
If your company supports a third-party storage provider, from the Teams tabs or some different apps, the data associated with them are saved instantly in the systems of that third-party client.
Manual Teams Tenant to Tenant Migration
Manually executing Teams Tenant to Tenant migration requires a big amount of IT expertise and time to complete it successfully. The shortage of public APIs from Microsoft restricts the automation of Teams migration. As there are no other methods for transferring Microsoft Teams from one office 365 tenant to another, we at Apps4Rent can create a plan that includes systematically moving each of the Teams elements to the new Tenant and then integrating them again into their duplicate Teams. There are many benefits of using Hosted Virtual Desktop as well.
Teams components to be moved and reintegrated
The elements of Teams are not sorted group-wise in the tenant storage. Rather, they are ordered by the type of content. While this keeps the data structure perfect while managing Microsoft Teams, it appears to be the bad part too when you choose to move them.
