What he said. I was just stumping until those experience chime in.I would not water in the days before collecting it. Because the mud on the roots will rip the roots apart when moving the plant. It's too heavy.
For all the rest, I agree with @dbonsaiw except for trimming back roots; it's not destined to go into a pot so I'd keep as much roots as possible.
Water heavily afterwards and make sure you fill all pockets in the soil. Then leave it to dry and don't water it heavily again, just moderately. You want the soil to dry a bit in between watering, because those wounds need healing and too much water can cause bacterial blooms, especially in freshly dug soils.
It's good advice you gave there!What he said. I was just stumping until those experience chime in.
@GroovyGreg Yes…electric underground will need serious attention. Or a gas line if the light post is natural gas. If it gets or looks problematic it’s simply time to cut it down at ground level and let it go. Be very careful again with electrical or gas connections. You really don’t want a bigger problem. Win points with your wife for the elimination of the tree. There’s no points for getting electrocuted. Don’t do something dumb.Also, be careful of the underground electrical wires running to the lamp post.

A tree that size will need a substantial amount of roots to survive transplant. Do not underestimate the size of the hole you need to dig to extract the tree. At least as far out as the canopy and probably 2-3 feet deep to get under to cut down growing roots. (and also allow similar hole to plant it in). That's a lot of digging!
Also allow for the weight. Live wood and leaves is heavy. One person will definitely struggle to move a tree like this even with no soil on the roots. With some soil attached it will be way more than 2 strong men can manage.
I would not attempt to move a tree this size without suitable machine assistance.
