Recently wefwef.app added an option to add the link to all of your reddit subscriptions (multireddit link from old.reddit) and search for replacement subs. You can pick which communities/instances you want to subscribe for each sub.
You should know this because it can make your life easier if you want to search for communities you’re familiar with.
I’m fine with starting over. My subscribed subreddits list was cluttered with useless subscribtions I never looked at. Now I can actually start a subscribtions list that is usefull… ah shit, I ain’t fooling myself. It’s gonna end up the same, but I’m fine with that.
