Find a text and if condition matches then replace it

Need a script that can find text in a file and replace it accordingly.
This is the file I have:

Code:
while IFS=',' read -r f1 f2 f3
do
{
nohup /home/testuser/dbmaintenance/sys_offline_maintenance.sh $f1 $f2 $f3 > $f2.out &
}
done < "/home/testuser/dbmaintenance/week1offlineserver.txt"

In this file I need a script that can look for the number after week in week1offlineserver.txt and replace it like: If number is 1, change it to 2, if number is 2 then to 3 and if it is 3 then to 4 and if it is 4 then to 1.
