Migrate bitlocker from Mbam to sccm with TPM key

Hi, We need to Migrate Bitlocker from MABAM to SCCM (Mbam integrate) but I can't seem to find information on if it will move the TPM key to SCCM or not.

We are running SCCM 2002 (soon to be upgraded to 2009)
MBAM server is 2.3 (We are in process of upgrading this to 2.5)

We would like to integrate MBAM with SCCM but also migrate recover key + TPM key.
I know recovery key will be moved but will the TPM key moved too, if not how do I move the TPM key without re-encrypting the drive.

Hi @lalajee

Are you referring to TPM startup pin on the device?
If yes, that is specific to device and it is stored in TPM chip present locally on the device. So your during migration you don't have to worry about TPM pin. Just make sure the policy are replicated and there will not be any need for reencryption unless there is a bitlocker policy change

There's no such thing as 2009 and never will be (at least not prod versions).

Are you referring to the TPM Owner password? If so, why are you escrowing this at all? By default, Windows doesn't even store this -- it sets it and then throws it away.

Sorry, not sure what this comment means. Why do you want the owner password stored? As noted, Windows itself no longer does this so it's not even available to be stored anywhere.

@lalajee , TPM owner password is not stored remotely . As @Jason-MSFT mentioned it sets and discards. Please refer the below microsoft document for your references.

https://docs.microsoft.com/en-us/windows/security/information-protection/tpm/change-the-tpm-owner-password#about-the-tpm-owner-password

Password sets and discards -Starting with Windows 10, version 1607, Windows will not retain the TPM owner password when provisioning the TPM. The password will be set to a random high entropy value and then discarded.

Password can oly be stored as a file -"Then you can create a new password, either automatically or manually, and save the password in a file or as a printout."
