How do I change my iCloud Apple ID from one account to the other?

Question

I have two Apple IDs. I want to rationalise iCloud on my devices, but on my iPad I am signed in with one ID and on the iPhone and Mac it is the other. I want to sign in with the other ID on the iPad as well, but I can't find a way short of deleting the account. Do I 'Delete account' on the iPad? WIll I lose my contacts etc? It's giving me that warning. And will it delete that entire Apple ID, or just its connection to iCloud?

Welcome to the Apple community.
When you delete the account from your device, you will be given the opportunity to save Safari data, reminders, calendars and contacts to your device, which you can later merge with the other account once you login.
You won't be able to save your photo stream photos in the same way, so if you have any photo stream photos that are not already in your camera roll, you should move them there before you delete your account.
Your iWork documents can be saved to iTunes on your device, but if you have them on a Mac they would be much easier to save to your desktop there. You can move them back after you switch.
Notes can be shared to messages or mail and copy and pasted back after the switch. Although if you have a Mac, you may find it easier to do there. You could also use a temporary secondary account (see last item) to log into both accounts and copy and paste directly into your other account.
You can set up Mail forwarding at iCloud.com mail preferences (little gear icon-bottom left) to receive mail from your old address to your new one.
As an alternative to just switching, you might consider switching and adding your previous account back as a secondary account at settings > mail, contacts, calendars. You would still need to move your photos and iWork documents and save your safari data, but you'd have access to your old mail, contacts, calendars, reminders and notes.
