I have just upgraded my computer to a new one and I had a whole lot of appointments in my lightning calendar plug-in in Thunderbird. I did not export my calendar when I had my old computer, I just stopped using it and started using the new one thinking that I could just grab the folder where the calendar is and restore it into my new one and get all my appointments back; but that did not work out. I copied the local.sqlite, which contains all the records of the events, but it still did not pull anything to my calendar. There's a forum that suggests me to copy the entire profile into the location of the current one, but there have been new events and e-mails that after the replacement of the computer that need to stay where they are; I just need the old events appended to the current profile, and if I replace the whole profile, that will delete my current events. I also tried importing the records in to the current local.sqlite database file and that did nothing either. Any help is greatly appreciated, Zac
