    I'm running Sierra with FileVault enabled on my 2017 iMac with an SSD. FileVault is also enabled on an external mechanical hard drive that contains my Time Machine backups. Will the High Sierra installation maintain the encryption of both drives? Does it have to re-encrypt the drives?

    They will remain encrypted and will not need to be re-encrytped.

    I went through this exact upgrade myself.

    I went through a similar procedure when I upgraded from Mavericks to High Sierra. The only thing that has left me wondering is if the recovery key changed at all during this process. I was not given any type of notification one way or the other, I can only assume that it remains the same as previous.

    Can anyone please confirm this, thank you.

    The recovery key does not change. You can verify it using this Terminal command:
    Code:
    sudo fdesetup validaterecovery
