I have WhatsApp downloaded via an old AppleID and I can’t remember the AppleID password or recovery phone number to reinstall it on my new phone - if I delete it and reinstall it on my current AppleID, will I lose all the old chats etc?

Hello, asim01.
Welcome to Apple Support Communities.
From your post, we understand you want to know about restoring your WhatsApp chat history using a different Apple ID. Check out this link from WhatsApp regarding your chat history: How to restore your chat history
"Restore your chat history from an iCloud backup
Verify that an iCloud backup exists in WhatsApp > Settings > Chats > Chat Backup.
If you can see when the last backup was performed, delete and reinstall WhatsApp.
After verifying your phone number, follow the prompts to restore your chat history.
Note:
You must be signed in with the Apple ID you use to access iCloud and iCloud Drive must be turned on.
There must be enough free space on both your iCloud and iPhone. You need to have at least 2.05 times the space available in your iCloud account and on your phone than the actual size of your backup.
The phone number used for backing up and restoring must be the same. You can't restore the chat history from another WhatsApp account.
Because backups are tied to individual phone numbers, it is possible to have backups for multiple WhatsApp accounts stored in the same iCloud account".
Any further questions about this, contact the app developer: How to contact an app developer
Cheers!
Thx a lot!
