Migration Throughput - Peter Caldecourt - Binary Tree

Migration Throughput:

Migration Throughput… image-5.png
Over the years of being involved in migrations the same topic is always brought up of how quickly can we migrate, and what throughput results will we see during "OUR" migration? This is a tricky one to answer, as whatever number you provide you will be held to this. For throughput results it really depends on many factors including the following, network, source and target environments, and the type of data being migrated. Oh and if you are migrating to Office 365 this will throw a few more challenges in, and if you are migrating from Lotus Notes to Exchange on-premises of Office 365 depending on the complexity of the data you are migrating for example recurring meeting and custom patterns can take longer to migrate. As you can see there are a lot of unknowns, and challenges to think about before you say how much data throughput you will see.
Migrate Everything Now!
Customers will want to migrate everything now, or as soon as possible so they can be up and running on their new investment and gain increased productivity from Office 365. However, depending on how many users the customer has we will need to set expectations that this can take time to migrate everyone to the new environment especially if coming from a legacy system like GroupWise or Lotus Notes.
With most migration solutions you can scale the migration infrastructure to meet how many users you want to process of an evening, however we need to add some considerations of how many users can your help desk support the next day.  If you are an enterprise company we may want to take a steady pace of doing the migration so we do not burn out your migration team. There are many ways of how to migrate your company and that is detailed in my migration planning blog. What we want to focus on here is that you should test, test and test to see what throughput results you get for your migration. This way you can then plan accordingly.


Remember you can always have coexistence in place for those business critical applications and so users from source, and target environment can still communicate during your transformation to your new investment and in this case Office 365. This means that you can take your time and migrate your users at a steady pace, and once you are getting the hang of things you can start to increase the velocity of the migrations.

Successful Migration


What we have to do is guide our customers, and partners to validate the throughput numbers in each specific migration project as this number changes from project to project. What we want to make sure is that we set expectations early and help guide and advise the customer on what we should do in their specific case. At the end of the day we all want the same results and that is for a successful migration
