There are two mistakes.
1. You must also set OFS to / otherwise the modification of $5, causing a rebuild of $0, uses the default OFS (output field separator is a space).
2. There must be a space between -v and z=

Not important here: gsub tries multiple substitutens, sub is sufficient here.
And there are bugs with brackets if the first argument in sub or gsub is in quotes. Better use slashes as first choice.
Code:
nawk -v z="Peoccam.20140613" 'BEGIN {FS=OFS="/"} {gsub(/Peoccam/,z,$5) ; print}' /home/mdadmin/test_ca
