New Tank Build and Livestock migration

[Afm32607]

So I will be transitioning a 91 Red Sea Reefer SPS to a 340+ gallon tank in the near future.

Obviously fish are simple, but some of my SPS are rather large colonies. For example a tri-color acro that is 8"x 4" across and 5-6" high and I'd like to keep the entire colony; however, the coral has a 1-2" thick stem that is no longer encrusting (due to shadowing?), and I am concerned that when I move it the base will not be able to regrow on the new rock work. Existing rock work is not compatible with the new tank will not be entirely transitioned (it was initially scrap rock that I used to see if I could do coral, fast forward a few years and you can still tell it was extra pieces).

My plan is to just use a tile saw to cut off the base and transplant that to some epoxy in the new tank. Will the epoxy curing process (which generates significant short term heat) harm the coral? Will the coral be able to encrust a base without getting a lot of light (the current base is largely brown in coloration)? Do colonies do better or worse than frags during a transition? Should I sell the colony and just keep the frags?

Any other tips from experience would be greatly appreciated.

If possible, you could keep a small portion of the dead part of the base, so any heat from the curing won't affect live tissue. Given light and flow, the tissue should grow down and eventually encrust onto the new rockwork. Just like frags, they always seem to grow down a bit and grab the rocks...if the light can get to it.
Of course, you could cut the colony up a bit, since you'll have so much more landscape in the new tank, and spread it around.
