Lift and shift is a cloud migration strategy which involves moving your applications to the cloud with little to no modification. For example, you have an application running on a server in your data-centre, you then deploy a VM in the cloud with a similar spec and install the application.
It's usually done to avoid the engineering cost of making the services more cloud native. What tends to happen a lot is that after a considerable portion of the migration is completed, the cost of the lift-and-shift effort start to overtake the savings, and the projected costs, dwarf the future savings.

I suspect this is what happened with Linkedin.
