“Beyond the technical capabilities, the time savings and reduced risk were the biggest wins. What could have been a complicated, multi-week project became a structured, stress-free process thanks to ShareGate automation options and smart checks.”
“I find ShareGate's overall UI very intuitive and easy to navigate, which makes my tasks straightforward. I particularly appreciate the reporting on data migration success; it's clear and concise, so I don't have to search around in the UI to find the specific task I'm trying to accomplish.”
“I love the easy way to get reports and the ability to transfer content without losing any metadata using ShareGate. It saves me a lot of time because manually transferring content is time-consuming and can cause metadata loss. Also, the initial setup of ShareGate was seamless with no hassles at all.”
