The Whys: Migrating From G Suite to Microsoft 365 (Office 365)

Familiarity: The older giant beats Google with an incomparable adoption rate in the business community. Most of the now professionally active folks literally grew up with Microsoft. It reduces the precious time spent for communication and coordination. This helps reduce adoption effort and re-training costs. Also, if you have to send any files around, and an external partner is on your mailing list too, you’ll have to get back to the good old Microsoft formats. 

Desktop-friendly: Do a majority of your employees use desktop computers? Well, Microsoft 365 shines in that department. G Suite is essentially web-based. It falls short when compared with the proven offline app support of Office 365. Particularly the Outlook desktop client and OneDrive.

Collaboration mechanisms: Yes, we’re talking about Microsoft Teams. Although file collaboration solutions of both platforms are pretty much identical, Microsoft managed to create a real enterprise working hub: the Teams app. It has no alternative on the market so far.

Scalability:  Your organization is growing. You need a SaaS platform with proven scalability. An area that Microsoft 365 (Office 365) shines in. Apart from offering a variety of plans to suit every organization size, it also has inherent Azure support for effortless scalability. It can grow with your organization.

The Hows: Migrating From G Suite to Microsoft 365 (Office 365): Buy-in, Scope, and Timelines

Before you go ahead with the technical part, understand the needs of your company. Remember, that you do not only migrate data, but entire business workflows that impact daily routines and productivity. A robust migration plan is the first step to minimizing post-migration turmoil.

  • Get stakeholder buy-in and migration champions. Cannot reiterate how essential strong stakeholder buy-in is to help smoothen hiccups along the way. Cultivate department-wide Office 365 experts who are aware of and fully convinced of the advantages of using the new platform.
  • Understand the breadth of apps being currently used. Map the working procedures and features from G Suite with their twins in Office 365, or find a good alternative.
  • Chalk out the timeline and scope: With rare cases, you may need to migrate everything in one move. However, a gradual, staged migration mitigates risks. Strongly consider a pilot migration to get org-wide support for your plan.

A final rollup before jumping in

Congratulations, you have a put stressful preparation phase behind you with these deliverables:

  • A schedule that clearly reflects your chosen type of migration: staged or cutover.
  • In case of a gradual migration, you’ve defined batches to be moved separately.
  • You have a list of essential native Microsoft or Google tools, as well as of the third-party vendors.
  • You’ve even arranged a disaster recovery plan.

A tick in each of these to-do boxes? Then, let’s take off!

Final Check! Secure Your Office 365 Migration

G Suite and Office 365 are exceptionally secure. But SaaS protection is a shared responsibility. They cannot protect you from causes of data loss at your end or from the occasional outage or downtime. (Free Ebook: 7 Reasons Why Enterprises Need SaaS Backup). This is particularly true during a migration. A colleague may have forgotten to ask for including deleted calendar events into the migration plan. Or some users suddenly realize that some Drive files disappeared from the trash bin before the migration, just due to their expiration date. You do not want to add to the stress of an already stressful migration with the fear of data loss. So how do you secure your Office 365 migration? With SaaS backup and recovery.

Everybody runs to you the Admin and pleads for recovery. You saved the day (and valuable data) by securing Office 365 with backup and recovery. You’ve backed up numerous data snapshots from all G Suite accounts, so no one needs to feel sad about their lost recycle bins. You open CloudAlly, choose the backup you want, hit “Restore” and <humble nod> at the applause. 

Some users may approach you with more extravagant requests. For such cases, – and for anything you could not solve by yourself! –  you simply ping our Customer Support Hub. We are ready to talk, chat, or exchange e-mails with you. A request from any communication channel, including a support ticket opened via our online form, will be equally valued. 

 After the migration period seems to be over, you do not give up your data protection best practices. Without changing your data recovery partner, you simply switch to CloudAlly’s Office 365 backup. Thus your entire migration from G Suite to Office 365 is completely secured from data loss.
