Objective:
To migrate WA and chat history from Android to iPhone.
To have dual WA run on iPhone 1.

Current Setup
iPhone 1 - Personal Whatsapp
Android - Business Whatsapp
(Technically we can't migrate WA from Android to iPhone but it can be done if it's a new iPhone)

Plan
1. Setup a new iPhone 2
2. Migrate Android WA -> new iPhone 2
3. Install WA for Business on iPhone 1
4. Move the Android SIM card to iPhone 1
5. Restore the WA Business on iPhone 1

Has anyone done this before?

Note:
Tested scenario.
iPhone 1 Personal WA remains.
Install iPhone 1 with WA Business and move the SIM card. the WA retained all the chat and group but chat history will not be migrated.

Perhaps can try using the Move to iOS method as well using this guide?
