Can I get assistance transferring data from old iPad to new if old is dead?

Unless you are able to restart your iPad to a running state - and successfully enter your Passcode - you'll not be able to recover any data from your iPad.

iPadOS uses an encrypted filesystem. Successful entry of your iPad Passcode unlocks the Secure Enclave (this being your iPad's security chip) within which the only copy of the encryption keys - that are required to access and decrypt your data - are stored.

Unless you have a pre-existing backup of your locally stored data, anything stored on your inoperable iPad will remain beyond reach. However, any data that has been synchronised with iCloud may still be accessible from iCloud itself:

If you value your data, always keep a backup.

If the old iPad does not power on, then data cannot be transferred from it.

If the old iPad was backed up through iCloud, the data can be restored from iCloud to the new iPad.
