converting iTunes library on Sierra to iMac pro Monterey

hello,I have an iMac mid 2011 on Sierra with iTunes. I bought a second hand iMac pro running Monterey. my iTunes library is on a separate disk not in the usual iTunes folder. how can I move my entire library and keep playlists and smart playlists intact? I only have 50Gb iCloud and my library is more than 400Gb.Thank you for the help. kind regards Peter
