Is software updates necessary on 4S before switching on to iPhone 6?

[iMore Question]

Hi, do I need to go for software update for my iPhone 4s from 7 to iOS 8... Before transferring my data through iCloud on new iPhone 6? If not will I lose my data while transferring ?

No, but it is recommended that you do an iCloud and/or an iTunes backup beforehand. That will allow you to restore your current data, pics, settings, etc., to your new device.
