I moved my thunderbird profile folder from my old XP machine & renamed the wordpad line in the file next to the profile folder to match the new profile name, so that worked ok to migrate my e-mails to my new windows 10 machine. Now I can't see my lightining calendar on my new thunderbird, and was wondering if there's a way to migrate the lighting calendar over as well. I suspect I may already have it somewhere in the profile folder as a folder/file on my flash drive since I have the entire profile folder on my flash drive for the thunderbird migration, but not sure how to use this. I read lightning is now integrated into thunderbird, but I didn't see this as an option in the new thunderbird yet.
