Tank Transfer/Upgrade

[Magma]

Ok so I have been reading all day about upgrading and transferring tanks.

I have in my 35gal system right now, about 60lbs of live rock which I have had for 2 years in that tank. My new tank is 125gal with 50lbs of base rock in it and ~200lbs of dry sand.

I want to take all my fish, corals and rock from the old tank and place them in the new tank. I have spent the past week getting the 125gal up to the same temperature and salinity as the old tank.

The tanks are less than 4 feet apart so it will be pulling the LR out of one tank and turn and place into the new tank will this be a problem? So many mixed views on this im just worried about losing a fish or coral.
