Alessandro,
Here is an input that should help you to start from existing movecs (referenced as oldrun.mos in the following input file)
start he

geometry
 he 0 0 0
 symmetry oh
end

basis small
 * library sto-3g
end
basis large
 * library ahlrichs_vtz
end
#I am assuming the molecular orbitals from the previous run are called oldrun.mos
set "ao basis" small
dft
 vectors input oldrun.mos output small.mos
 noscf
end
task dft  

set "ao basis" large
dft
 vectors input project small small.mos output large.mos
end
task dft
