Inventory assessment

Having a detailed inventory analysis is crucial to your enterprise tenant migration as it helps you have proper oversight of the existing tenancies and objects that make up your digital estate. A robust migration tool like AVAMIGRATRON can provide you with a detailed inventory of what you have and what you need to bring to your target environment.

Tenant-to-tenant migration is a perfect chance for your enterprise to start off your newly merged tenant on the right foot. And having a detailed inventory will help you eliminate duplicate and invalid content that can probably be deleted or archived. We also fetch the inventory of both environments so that we can easily estimate the efforts required and help you decide which will be your source and target tenants.

Get a complete inventory of your SharePoint Team (Site collections, Sites, Lists and Libraries, pages, shared files, tasks, file size, documents, custom solutions, and much more) MS Teams (channel list, public/private channels message, attachment volumes, and group/direct chats message volumes), mailboxes (name of the user mailboxes, folders, etc.,) and OneDrive (files attached to private chat sessions, meeting recordings and organizational document libraries).

Preparing the source and the target tenants

Before kickstarting with the tenant migration, we erase the primary email domain from all the objects in the source tenant. By leveraging the details in the inventory, we estimate the available space in the target tenant and increase licenses to ensure a successful migration from your source tenant.  According to the requirement we also create administrator accounts in both the tenants to optimize the data throughput.

Identifying and fixing potential issues

Apart from strategic planning, inventory, and preparation of the source and target environment, an efficient tenant-to-tenant migration also involves identifying and fixing potential issues. Identifying and fixing potential issues will not just repay in long run, it will also minimize the downtime and enhance the destination environment making it a whole lot easier to manage.

For example, when the items in the source SharePoint Online tenant have unique permissions, they can’t be migrated as such. In such cases, we manually recreate the permission levels on the destination SharePoint sites to enable a swift transition to the target tenant.

Successful migration

The key to a successful migration is to communicate clearly!  After identifying and fixing the potential issues, we discuss with your IT teams their priorities, and deadlines, and channel the migration process accordingly. To ensure data accuracy we perform data validation testing to ensure all your data is transferred without any data loss. We also determine the best method for migration to mitigate downtime and enhance your migration process.

Delta migration

All the additional mail growths, modified data, and messages exchanged during the initial migration must be migrated to the target tenant. Instead of going for a full migration to retain those last-minute messages, we filter your data right from the date on which you completed the initial migration.

Our incremental migration capabilities will ensure that you are moved to your target tenant with what’s needed and nothing additional.

Content verification and domain cutover

Once we pre-stage the content in the target tenant for each workload, we execute your final content migration. We reassociate domains from all the source objects to register and validate the domain on the target tenant. This will be followed by reconfiguring the Azure AD Connect to the target tenant. Once done with Azure AD reconfigurations, we disable exchange hybrid connectivity to the source tenant and configure it to your target tenant. We follow cutover migration best practices to overcome unexpected downtimes and help you make the move without any business interruptions.

Support

Since we clearly analyze your tenant architecture and plan your migration, you will experience a hassle-free environment right from the first day of the migration. However, once you have achieved a successful migration, our team will also provide two weeks of 24/7 support to make your transition even more seamless!
