How to get the desired output

I am getting an input from a shell script, something like: 

USER1_OLD:USER1_NEW,USER2_OLD:USER2_NEW ....

The number of key pairs can vary. I need to get output like: 

USER1_OLD,USER2_OLD,......

One way using awk:

$ ./script.sh | awk '{printf "%s",NR==1?$1:","$1}' FS=: RS=,
USER1_OLD,USER2_OLD

It's not clear if you want a trailing comma, if you do the script can be simpler:

$ ./script.sh | awk '{print $1}' FS=: RS=, ORS=,
USER1_OLD,USER2_OLD,
