Idemia Success Story

Matthew estimates ShareGate saves him at least 6 hours for every 20 tickets he resolves.

ShareGate has helped us increase IT efficiency and allowed us to put more time where we are needed most. On a smaller migration, ShareGate saves me hours. On our main cloud migration, it gave me weeks back!
