Changing Persistent settings from roamable to local without breaking something

Since like forever, the Key Promoter stores its statistic about clicked buttons using a PersistentStateComponent. One problem I had not thought of is that this leads to merging errors when people try to sync their settings to different machines. 

My idea is now to change the current persistent state annotations to this:

@State(
    name = "KeyPromoterXSettings",
    storages = {
        @Storage(
            value = "KeyPromoterXSettings.xml",
            roamingType = RoamingType.DISABLED
        )
    }
)
public class KeyPromoterSettings implements PersistentStateComponent<KeyPromoterSettings> {...}

Question: Will this break something or is this transition smooth for all existing users that already have the Key Promoter?
