Moving to the cloud was a smart move!
At first you probably weren’t really sure, and had some concerns, but you’ve finally made the move to Office 365.
I bet you thought this would be your last big migration for a while. Where could you possibly be moving to from here anyway, right?
One day, your boss knocks on your door and says that the company is merging domains following a recent acquisition with another company, who is also hosted in Office 365. What happens then?
Well, as part of the Sharegate sales team, this is a scenario I'm familiar with and hear about on a regular basis. The goal of this article is to point you towards the information you will need to get started and to make sure you've considered everything to make your move a success.
Planning and Preparing for an Office 365 Merge
The idea of having to migrate once more can be disconcerting but fear not, we’re here to help.
So how does a migration between two Office 365 environments even work? More importantly, what can you expect from this type of migration?
You'll be happy to know that it is possible! Here are the first steps on tackling this type of scenario.
Like you would with any other migration, you should prepare accordingly. The Sharegate tool provides different ways for you to do so, and to make sure you keep on top of things:
- Run the Inventory feature in order to build an inventory of everything found in your SharePoint environment. Knowing what you have, and where, will help you assess what should and shouldn't be moved.
- The Essential Office 365 Migration Checklist is the best way to make sure you don't forget a thing when performing your migration. Download the eBook and check off every step as you go along.
- As for our Pre-Check Report, it allows you to simulate your migration and address issues that might occur, without having an impact on your actual live environment.
What to Expect During Your Migration
Let’s be straight, no one thought that once they would migrate to the cloud they would actually have pack up and move again! It’s like a bad breakup you didn’t see coming. That being said, migrating from Office 365 to Office 365 does come with some complications.
Moving SharePoint and OneDrive for Business Content
As we know, Sharegate can seamlessly handle a SharePoint to SharePoint migration and can also help move your users’ content from OneDrive for Business to OneDrive Business. Here is the step by step to follow.
Moving Office 365 Groups Content
Office 365 Groups being as popular as they are, you probably have some in your environment and their number count is growing by the minute! So, what will happen to them? Can they be moved from one tenant to another? They can be but it’s not a seamless process.
We recommend that you first identify the Groups at your source and create the ones you want to keep, at the destination. Once this is done, Sharegate will be able to migrate the SharePoint content from each Group. Ideally, you don’t want to bring permissions over with the content, simply to avoid any complications.
To get a better idea of what you’re looking at, list and identify your Office 365 Groups in our Explorer before migrating.
What About Speed?
There’s no sugar coating it, moving between Office 365 will be slower. Much slower.
When migrating from one Office 365 tenant to another, our main bottleneck is caused by the way we fetch both structure and content information from your source tenant. At this time, the migration API is only available when writing to a destination environment and all information extraction from your source must go through the more traditional client-side object model.
Sharegate has mechanisms in place to avoid being throttled by Office 365, but we must still limit the number of simultaneous requests we send your source environment's CSOM to prevent additional slowdown. This is why an import from a file share or a copy from an on-premises environment to Office 365 is much faster than a copy between two Office 365 tenants.
…This is also how your patience will be tested!
Knowing this, what can be done to avoid growing unnecessary grey hairs? Migrating during off hours is definitely your best chance at gaining as much speed as you can. You’ll also want to make sure your bandwidth is at its strongest since the operations are all done online. Other measures can be taken to optimize your speed or are at least worth reviewing before any type migration.
Finally, to make sure everything was brought over at the destination, simply run your migration report.
Stay Alert and Keep Your Content Secured
So, you’ve made it to the cloud, once more. The merger was a success and so was your migration.
Awesome! What now? Even if you’re done with your migration, you’re never done managing your environment. After all this hard work, upkeep and management is the next big step.
If there’s one place where things move quickly and you want to be on top of things, it’s in Office 365. Here are a few things you might want to keep an eye on or do on a regular basis:
- Manage User and Object Permissions
- Security Auditing
- External Sharing
- Manage O365 Groups
- Schedule Reports
