Welcome to DW! I have an alternate (specialized) journal that I hadn't imported here and I set it to importing on Friday. It had finished by this morning. So based on that, I'm guessing you might be waiting a couple days.

As for what to do about the LJ account, that depends. My LGBT friends seem to be mostly deleting; that's a community that Russia oppresses and suppresses. Some of my privacy-minded friends are deleting, though that ship sailed, at latest, when the servers moved to Moscow in December, so this seems to be a "final nail" situation rather than actual protection. Some of my other friends are deleting on general principle or in solidarity. Other friends, however, are leaving their journals there but not updating them any more. And a few are still posting or cross-posting there.

I have some external links to my journal (specific posts, mostly), so I'm going to try to fix those first. I still have a few friends who post locked material that I want to be able to see, and that won't work if I delete the account, but I might delete all its content and leave the login. I haven't quite figured it out yet. I'm done posting there, though; I haven't accepted the TOS.
