Office 365 is a nearly ubiquitous cloud-based productivity suite from Microsoft. It includes virtually every familiar information worker productivity tool. However, the big question is: how long will it take to migrate from my current on-premise or existing cloud-based tools.
In the linked blog article, I provide some guidance on what you can expect.
The timeline for any organization's Office 365 deployment is dependent on the situation. The parts of Office 365 that require the most time are mailbox and content migrations. Most other services -- such as Teams, Groups, Skype for Business and Office client -- have fewer legacy connects and merely require configuration or deployment. The remaining features are usually just enabling and change management.
