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:
Follow the normal steps to migrate SharePoint content or site objects.
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.
