On your OLD account:
1. Export your follows, mutes and blocks: go to Settings, then Data Export, then download the CSV files (you do NOT need to request an archive to do this!)
2. Set your old account to redirect to the new one: go to Settings, then Edit Profile, then "Move To A Different Account" (at bottom of screen)
On your NEW account:
3. Upload your follows, mutes and blocks: go to Settings, then Import, then upload the CSV files
