You either need to move the keys to s new machine, basically use an unlock utility that can with the software to put it on the new machine. Or you need to backup the data to a unencrypted dive, move the drive, reimage with your OS and software, pull down the data.
Likely you're going to go with the second option.
If you're not using a disk lock utility like check point or end point, AMD just have tpm enabled then you're duce isn't encrypted. It doesn't sound like you're very familiar worth this stuff. ...pleb

I'm not. That's why I'm asking. So a full disk image with TPM disabled would be fucking useless?

TPM is NSA botnet.

Um, did you mean Windows Bitlocker?

If you did, according to the docs, what you need to do is to use the Bitlocker recovery code when you put it in the new machine. It should then be able to decrypt (using the recovery code), and once you've done that it should, in theory, be able to copy a key into the new TPM.

You may wish to suspend Bitlocker first and then turn it on. If the data is valuable and you don't want to lose it, I do suggest doing that. At the very least, take a (secure) backup first. TPM-held key management is not an easy thing to move to another hardware configuration - deliberately!

If you meant something else, like Linux dm-crypt-related stuff, that depends on how exactly you're doing your key management (trousers?).

No, I meant TPM. It's a BIOS setting on Surface Pros and Bitlocker is not enabled, but the partition is still encrypted

TPM is not the same as encryption. Disk decryption keys can be stored in the TPM using something like Bitlocker and maybe some other full disk encryption software, but having/enabling a TPM in your system doesn't mean your disk is automatically encrypted.
If you're on Windows, it also uses it to prevent unauthorised changes to the bootloader to help guard against rootkits and such.
