Viprion query

Hi

I have 2 Viprion hosts (each standalone with 2 blades) having 3 LTM guests configured on them.These guests are in HA pair across Viprion hosts.

A particular guest has settings- core per slot =8 ,on slots 1 2.

I would like to limit the number of slots from 2 to 1 so that only one blade cores should be in use for that particular guest instead of 2.

I need to know if this change could be done in production environment without any outage ? Can there be any service impact ?
