How do I migrate my Transmission torrents & settings from an old Macbook to a new one?

How do I transfer my **Transmission 3.0 torrents, torrent data files, and colour tags/labels** from 1 Macbook Pro to another. - My old Transmission app is in the old Macbook Pro MacOS boot ssd on a 2.5" OCZ vertex 4 ssd ~128GB. The actual torrent data files, 960 GB of anime, is on 2.5" HGST HDD 1000GB inside a macCaddy in the Superdrive slot. MacOS El Capitaine. - I plan to remove the MacCaddy and HGST drive from the old MAcbook and place it into the new Macbook's Superdrive bay. - The new Macbook Pro MacOS Catalina boots off a 2.5" OCZ 460 Vertex ssd ~256GB. How do I put transmission app settings into that drive and have it recognize the location of the torrents in the new HGST Hdd 1000GB drive? Note: 1. On my old Mac I customized it so that my **Home Folder** (Documents, Downloads, Music, Photos, etc) was stored on my huge 1000GB HGST Hdd, it is **not on the MacOS boot drive**. 2. Transmission automatically puts my anime torrents in my Downloads folder so my data is targeted to go on my HGST drive automatically. 3. This setting will be important to transfer from my old Mac to my new Mac.
