Sago palms do not like to be disturbed so any transplanting needs to be done with great care. Mature palms can be transplanted in early spring or late fall. Be sure to relocate the plant in adequate growing conditions--full sun, well-draining soil, etc. Include as much of the root system as possible when digging up and moving it. You may also want to consider trimming the plant back to prevent transplant shock.

Move it while it's dormant, take as much root system as possible. Stake it well in it's new home, it's going to be slow to root back out. Tie the fronds up and insulate the whole thing the first winter, depending on what zone you're in, if you're in Florida, don't worry about the insulation.
If you're not a landscaper, hire this move out, it's going to suck.
