Data/account transfer from old to new PS4 system

Plan D: buying new HDD + transferring data via ethernet cable to PS4 Pro 2+ TB

• buy a new 2-TB-HDD for the PS4 Pro (or even bigger, if 15mm HDDs fit into the PS4 Pro HDD cage)
• put the new HDD in the new PS4 Pro
• update the firmwares for both PS4s, so they are the same
• deactivate the old PS4 as "primary console" for all my PSN accounts
• connect both PS4s to the same LAN-network and power both up
• on new PS4 Pro: sign in to PSN (with my main account)... that should automatically start the data transfer screen  
• transferring the ~1.5 TB data via ethernet to the new PS4 Pro (probably takes 5 - 8 hours)
• activate the new PS4 Pro as "primary console" for all my PSN accounts
• sell the old PS4 with the 1.75-TB-HDD (slightly higher selling price than with 1-TB-HDD)

Especially if the PS4 Pro supports bigger HDDs than 2 TB, I'm tending to Plan D.

Do you see some errors in the procedures above? What are your own upgrade plans if you switch from your old PS4 system to another PS4 (PS4 Pro, PS4 Slim, a limited/special PS4-edition, a replacement for a broken PS4...)?

I'm currently tending to Plan D.

If the PS4Pro HDD cage is still too small for 15mm HDDs, I will probably buy this one for it:

It should be the fastest 2TB-HDD that fits in a PS4... it is the only 2TB-SSHD model available (existing?)
