One thing you should do is grab your data for easy moving, you haven't already.
Assuming you're using the default Lemmy web UI (not Voyager, or Photon, or a mobile app, or whatever), click on your username in the top right, and select "Settings".
On the settings page, there's a section called "Import/Export Settings". Click the "Export" button and let your browser download the file.
Then, when you switch instances, you can go into the same Settings page on the new instance, select the file you downloaded, and hit "Import" and you will automatically be resubscribed to the communities you subscribed to.
Thank you so so much for showing how to export it. I didn’t want to have to start from scratch in trying to figure out who I followed and who I didn’t. Appreciate it once and again.
Later on when you successfully sign up on a different Lemmy instance just go into your new user's profile settings again (exactly how you just did for https://lemm.ee/settings but it'll be [YOUR-NEW-LEMMY-INSTANCE]/settings, in there under "Import/Export Settings" look for the Import section and there you can import the file you just exported.
just find another instance and make an account there, I just moved from lemm.ee cause lemmy.today was recommended in the comments on a post about the shutdown.
