After family discussion, we're migrating Kuma's LJ over to DreamWidth first. It's much smaller than mine, so we're using it to get the hang of how to do the migration and setup. His account will be https://travelswithkuma.dreamwidth.org/. The import is currently queued. There's no surprise that there continues to be a long queue of users migrating material into DW from LJ.
I do not currently intend to delete my LiveJournal account. As a permanent member, I don't see why I should. Even if by some chance I manage to do something to run afoul of Russian law, I don't anticipate ever visiting Russia (despite the idea of taking the Trans-Siberian Railroad being intriguing), so I'm not sure how anything could happen other than my journal being deleted.
