Take time to discuss the importance of their role and to arrange a convenient time for them to work with the movers. Plan around application managers. Development and applications will come to a standstill during the back end move, and they will require adequate advance notice and a timeline.
Address issues your company may have experienced during a previous move. Discuss concerns and create a contingency plan if there are fears that the experience may be repeated. Set current baselines as a point of comparison for after the relocation.
