Data migration for replacing HDD with SSD - suggestions?

[Temlakos]

Everyone:

If you have followed my threads about:

SMB failing with F27

and

system hanging and requring repeated restarts,

then you've seen people suggest replacing my 1 TB HDD with an SSD. I 
acquired a 1 TB SSD and then tried to clone the HDD to the SSD. The 
clone /failed/. Reason: the disk is already showing some bad sectors. 
The outputs of satactl and fsck make that undeniably clear.

On the advice of a professional installer, I have since acquired an 
additional SSD (capacity 120 GB) and am now acquiring a mounting bracket 
and some power and SATA data cables. I also downloaded the F27 KDE 
Plasma 5 Spin as an ".iso" image.

My plan is to install F27 "clean" on the two SSD's, mounting the 120 GB 
SSD at root ("/") and the 1 TB SSD at /home. I must then migrate my 
data, browser cookies (Google Chrome, Firefox), e-mail 
accounts/saved/messages/other settings (Thunderbird), and documents, 
pictures, music, videos, and various downloads from the HDD to the SSD.

This machine has 8 GB of memory on board.

I now ask the community for some suggestions.

First, for partitioning:

1. Should I even try to accept /automatic/ partitioning when the 
installer gets to that point?

2. Is 120 GB large enough for the information on the other directories 
besides /home?

3. Should I create a separate /boot partition on the smaller SSD, and if 
so, how large should I make it?

4. How large should the swap partition be, and where should I put it? 
(That is, on the 120 GB or the 1 TB drive)?

5. In general, should I place a partition for anything other than /home 
on the 1 TB SSD?

Now, as regards data migration: I have three user accounts to migrate, 
plus another directory on /home called "lost and found."

1. Should I even try to migrate "lost and found," and if so, how?

2. I have at least two choices for migrating data and settings from the 
various user accounts--three for some of them.

     a. Connect the HDD to the SATA bus /after/ installing F27, and then 
force-copying everything out of each /home directory to its 
corresponding directory on the new configuration. (What command(s) would 
you recommend using, and with what options/switches/etc.?)

     b. Connect a large external HDD through a USB interface, transfer 
all the data to it before modifying the hardware, then re-transfer it to 
the system after installing the SSD's and F27.

     c. Migrate the data to its "temporary refuge" over a Samba network 
(possibly do-able for at least one account, and that's the biggest 
account) and then re-migrate to the new system?

Which choice would you recommend?

3. Is it worth migrating every single hidden file or folder? Or should I 
select only those folders that I know contain customization, account, or 
similar settings, plus my saved documents/pictures/music/videos, and 
migrate those?

Thanks in advance.
