Replace and add digit

Hello, 

I have the following situation - in the original files I have the following information in the field:
ServerName1
ServerName10

I need to replace the values in the output to be something like:
srv01
srv10

while I know that the following command does replace the ServerName to srv, I cannot seem how to add 0 digit before the numbers that are having only one digit:

| rex field=AIS_ServerHost mode=sed "s/ServerName/srv/g"

The output will be:
srv1
srv10

A bit of help, please?

Thank you!

hi @jugarugabi,
Apply rex command again to append 0 to values ending with a single digit.

| rex field=AIS_ServerHost mode=sed "s/ServerName/srv/g" 
| rex field=AIS_ServerHost mode=sed "s/srv(\d{1})$/srv0\1/g"
