updating iRule in live

I need to update an iRule that is working through a list of host headers to work out which pool the request needs to be targeted against, however this change has always been done at night when the system is quite and therefore I do not know the impact.

 

There are roughly 100 connections on the VIP at present, but I need to know what will happen should the irule change either by actually updating the irule (to include a new host header and pool) or if the irule was changed on the VIP (remove the current one and replace with the new one). Can anyone advise?

    Brilliant that is what I was looking for. I have been looking around for a while for that sort of answer. Thank you for the quick reply!
