This is good advice. I once participated in a move of clusters to a
new building  at an oil company. I was very, very impressed with their
professionalism. They had hired a moving company, who unracked every
node and wrapped it in bubble wrap before moving it across to the new
building. As a result the systems came back up without major problems.

Five year old kit is getting old and cranky, and should be treated
like your arthritic grandmother.
