“An exemplary cloud-based platform which offers a range of applications that boost productivity, creativity, and collaboration.”

What does come to your mind after reading the above sentence? It’s about either Office 365 or G Suite.

G Suite is a collection of all the cloud tools offered by Google, including Gmail, Drive, Sheets, Docs, Calendar, Slides, etc. It was rebranded in 2020 and is now popularly known as Google Workspace. While Office 365, now known as Microsoft 365, combines many applications on the cloud, including MS Office, OneDrive, SharePoint Online, Exchange Online, etc.

All organizations, whether small, mid, or big, now require cloud applications to manage their work and employees. Both platforms come from the same school of thought but still have a stark difference. And those differences have become critical factors in choosing between Microsoft 365 or Google Workspace. There are many hardcore facts that prove your data is secure in Office 365, but due to the regular improvements in features and security over the years, Google Workspace has become the user’s first choice. Many users and businesses are looking for methods to migrate from Microsoft 365 to Google Workspace.

Why migrate from Microsoft 365 to Google Workspace?

It is necessary to understand all the benefits which G Suite has to offer-

  • Better functionality- The prime reason users switch to Google Workspace is the performance of all its applications. They are well-known due to their speed and broad accessibility.
  • Familiar interface- One of the most significant advantages is that all the users are well-versed with the Google applications. We have been using Gmail, Drive, and Calendar for personal use for years now.
  • Simple subscription plans- A vast range of options always creates more confusion. G Suite has limited subscription plans like Basic, Business, and Enterprise, from which businesses can choose according to their requirements.
  • Unlimited cloud storage- Once your business flourishes, you need unlimited storage space, but if the service keeps charging for extra storage, it can become costly. Google Workspace offers all its Business and Enterprise plans to enjoy unlimited cloud storage.

How to plan for Google Workspace migration?

Office 365 to G Suite Migration is not just a simple transfer of data; it involves a complete change of environment. These are all the factors that one needs to take into consideration before starting the migration process-

  • Understand Google Workspace
    Before you get into the new platform, it is essential to understand all the nooks and crannies of Google Workspace. So, go through all the Google documentation and expert advice to learn more about Google Workspace.
  • Prepare a roadmap
    Due to many intricacies, you need to plan the entire migration roadmap, taking into account every detail. You need to understand both platforms, ensure data security, ensure a hassle-free migration process, and foresee the problems involved.
  • Understand the data-
    A suitable data migration procedure depends on the data you are dealing with. Run a deep check on all the users, files, and their sizes to be migrated from Office 365 to G Suite.
  • OneDrive migration
    The transfer of emails, contacts, and calendar information is easily carried out using the Data Migration Service. But the OneDrive data can only be migrated manually. Set up a proper plan to migrate this data.
  • Timely communication
    Ensure that you have a smooth communication channel throughout the migration time to avoid panic in any situation. You can even have an email id or thread dedicated to this communication.
  • Train all the users
    Every employee should be trained in the new productivity suite since the interface and processes are different. They might need guidance with some training and workshops.
  • Backup Office 365 data
    The most crucial part of the plan is to backup data selectively from Office 365 or entirely. This must be done at the earliest to avoid losing data. You can utilize the Kernel Office 365 Backup tool, which professionally backs up data. It is a professional tool that promises the security and integrity of data.
Migrate data from Microsoft 365 to Google Workspace using Data Migration Service

Data Migration Service (DMS) is a complementary utility available with your Google Workspace plan. Using the admin console, you can apply this facility to import the data into your new Google Workspace account from Microsoft 365. The selected data is copied and not transferred; hence, you can access it anytime at the source and destination.

Features of Data Migration Service utility
  • You can easily migrate email, calendar, and contact data.
  • The time taken to migrate will depend on the data’s size.
  • Files from OneDrive cannot get migrated using DMS.
  • Only one type of data (either Email, Calendar & Contact) will be moved at a time—conduct a separate migration for each item.
  • This approach works best when migrating data for 1 to 100 users. Selecting more users is possible but will degrade the utility’s performance.
