new and old iPad

Presumably you’ll want to transfer your data and settings from your old to new iPad. These support pages should get you started with setup of your new iPad - and the methods of efficiently transferring your data from old to new iPad:

Set up your iPhone, iPad or iPod touch – Apple Support

Transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support

Use Quick Start to transfer data to a new iPhone, iPad or iPod touch – Apple Support

If the donor iPad, from which you are transferring your data precedes iOS12.4, QuickStart will not be available.

“Transfer” is rather a misnomer. In reality, your data and setup is merely cloned to the new device. Nothing is moved or removed from the original device.

An alternative is to restore either an iCloud or iTunes backup to the new device:

When you are ready, the best procedure for preparing you old device for reuse by a different user can be found here:

It is generally inadvisable to just sign-out from your AppleID before giving an iPad to another user - as unintentional sharing (and merging) of sensitive and/or personal data can occur. As such, the iPad should instead be properly prepared and erased - and set-up again by its new owner - using their own AppleID.

Should you wish to do so, you can selectively share App and other Apple services using Apple Family Sharing:

I am getting a new iPad that i want to connect to my phone number, my old iPad i want to remove from my account or number and connect it to my wife's phone. I don't want to erase all the info on the old iPad. Just move it from my phone to hers.How do i do that

Thanks

1. Setup your new iPad, with your Apple ID and it will automatically get your number form there. Link-> Set up your iPhone, iPad, or iPod touch - Apple Support
2. You should not do this. All your apps and data are tied to your Apple ID, if your retain your Apple ID logged in to the old iPad all your data will be mixed up. All apps downloaded with your Apple ID will continue to require your Apple ID and password to update. If you really really want to do this and are prepared to handle the mess it will be, you will need to go to Settings->Messages and Settings->FaceTime, and log out of your Apple ID from there and log in with your Wife's Apple ID. Then messages and calls will be able to be received on the iPad from her number.

I really suggest you wipe the old iPad and set it up as new with her Apple ID to avoid a lot of issues down the road.
