MIgrate Old Thunderbird Profile to New Install

How do I migrate the old Thunderbird profile to the new Thunderbird? Background: Up until mid-Jan 2024 I was using Thunderbird on Windows 7. In mid-Jan I did a "clean" install of Windows and installed Thunderbird. Due to a corrupted Windows installation, I had to do another "clean" install of Windows 10 Pro. Today I installed Thunderbird version 115.9.0. Everything went well. However, I don't have access to my old - pre-mid Jan profile - which has e-mails and contacts I need to access. Here's my setup: Thunderbird installed in D:\Thunderbird New Thunderbird profile is in M:\Thunderbird Old Thunderbird profile is in M:\Thunderbird-OLD

How do I migrate/import the old messages, address book/contacts, and find out which extension I had installed?

Thanks.

UPDATE: Figured out how to import my old profile. Now I have 2 email accounts! How can I tell which one is the active and from which account (both have the same e-mail address!) should I move the content to the newest account so I can delete the old account?
