Hi @H_Kanchan ,
You can probably change the cookie name by using do plugin. You just need to call s.getNewRepeat as shown below:
s.eVar1 = s.getNewRepeat(30,'s_getNewRepeat_xx');
The first parameter says, days to expire the cookie. It does refresh every time user loads the page. Value will reset to "New" in case of site is not loaded for 30 days.
The second parameter is your cookie name. I would recommand to set xx value if multiple site is running on same domain.
If the cookie name is changing after the above change then the value also should be change. You need to wait for session to expire otherwise you will get same value(New).
