Well the tank move had its ups and downs, the nem took about an hour to move off the glass. I siphoned the water down to the foot and began to work the nem off with a credit card. as the foot came off I siphoned a bit of water and repeated the process untill the foot finally released.
The down part to this was that as I was siphoning the water I did not notice my other fish were darting around and they strayed into the nem, I lost a potters angel and a mimic tang and a dispar anthias, the nem coughed up the fish ( not the dispar) later.
The nem and clowns were transferred to a bucket with a portable bubbler attached. The guys who built the tank then moved it and a third of the water.
I put the new caribsea livesand in the tank and the rocks ( which have sps attached and were moved dry with a salt water soaked towel over them in a poly box, the corals were fine for two and a half hours out of the water!) and then gently filled the tank and switched on.
Two hours later I put the nem and clowns in, they settled in right away and went were I wanted them too

. So far the nem has not showed any signs of distress. However I can now attest first hand to why these nems are so delicate, the foot and column are very thin and how they are extracted from a rock in the wild, without being damaged, is completely beyond me.
Here are a few shots of the new setup, which will be a nem species tank primarily.
