Insane mode is a setting found in the ShareGate migration tool that allows you to migrate or import your content and objects faster.
When migrating to an on-premises environment, Insane mode offers significant improvements to migration speed by using the Server Extension for faster file uploads, helping you to save time.
To enable Insane mode for on-premises (versions 2007, 2010, 2013, 2016, and 2019), follow these 2 steps:
Step 1 - Install the Server Extension
At a minimum, install the Server Extension (version 1.8.3 or greater) on your destination on-premises server.
If your farm has multiple web front-end servers (WFEs), the extension must be installed on all WFEs.
Step 2 - Activate Insane mode
You can activate Insane mode in 2 ways:
When prompted to select the Copy options, toggle the speed to Insane.
Select Settings from the menu, then select Migration.
Under Migration speed, select Insane mode.
