Make sure to have someone available to properly refill and set the system at the correct PSI after you're done with draining and rerouting the lines. Make sure the person knows what he/she is doing with this routine.
Rerouting the line or moving the convector unit may turn out to be the easiest part.
You will have to shut down the system (shut off the power) and at least partially drain it so the portion you're working on is without water. When draining (presumably from the drain cock at the boiler), open up some of the bleeder valves in the upper radiators for venting.
If you have an automatic fill valve plumbed to the citywater line, and most such systems have this, shut that off first otherwise it will simply refill as you're attempting to drain the system.
Anyway, what I'm trying to suggest is make sure you or someone else knows what to do with the system AFTER you're done with your part.
It is very easy to get confused over what to do when refilling a system, especially with older setups with steel expansion tanks.
Speaking from experience having rerouted lines and understanding how our system works - but I am not in the trade and can't give detailed advice.
Hope this gets you headed in the right directio, though.
