I am looking to perform a GSuite to Office 365 Migration and went through the manual processes first. There are several ways of migrating data from G Suite to Microsoft 365, but I stumbled on some issues while trying.

For a manual and/or simple migration, one can export data from Gmail via takeout or Google’smigration options and import the required data to Microsoft 365. Similarly, one can also export and import calendar and contact information if the data to be migrated is small. This is ideal for few users with less data.

What are the common pitfalls?

Failure to verify the source and destination accounts (users) before migration

Missing attachments and old emails

Poor user/mailbox mapping

Duplicates created upon multiple user migrations

Failure to migrate calendars, contacts, and emails

Too many users to migrate manually.

Other complications can include authentication errors, permission issues, failed mailbox migrations caused by large data, or migration job failure due to huge data.

I stumbled on the Kernel GSuite to Office 365 Migration tool while searching for alternatives. The tool offers bulk migration and selective/incremental migration options to deal with large-scale data migration. Unlike the manual process, it does not require migrating each user’s data.

For a user that has performed a Google Workspace to Office 365 Migration before, what approach worked? Were they able to adopt the free/manual option, or was it necessary to invest in a migration tool due to the volume of data or users?
