Now that smaller instances are disappearing, which instances do you think will stand the test of time?

I had an account on lemmy.one and now the instance has been down for a day or two so I made this new account. I also heard other small instances are dead or disappeared.

So which ones do you think will actually stick around for a long time?

ALSO, does anyone know how to get my subscriptions from lemmy.one and import it here? TIA!
