Tech question for everyone leaving LJ.

I'm watching a mass move of my flist from LJ to dw.

Could I ask those of you who have made the move and backed-up/downloaded your data from LJ what you used to do this?

I have been using dw since 2009, crossposting all the while. One thing that has stopped me from making a clean break with LJ is that I haven't downloaded all my old posts and comments.

If you have useful suggestions on how I might do this, I'd really appreciate it if you shared them with me.

Thanks!
