How to move account from /home/home2 to /home and remove sub-directoy /home2 of /hom

Hello everyone,

My server has:
1 NEW 500 GB hard drive with the operating running WHM set as /home
1 OLD 500 GB hard drive set as /home2 which has about 10 accounts on it
1 old 200 GB hard drive set as /home3 which has about 4 accounts on it.

When I do command " rsync -vrplogDtH /home2 /home " when I was in root@server [/]# , but it turn out to be all the accounts from the OLD 500 GB hard drive were copied to /home/home2 but not as /home as I expected.

My questions are:
1) How do I move those "copied user accounts" from /home/home2 to /home ONLY ? or can I set in the WHM some way to make it recognize those accounts?

2) Those copied accounts don't show up in the WHM when I click on "List Accounts"

3) Old accounts on /home3 (of the 200 GB hard drive) also don't show up in the WHM in the "List Accounts"

What should I do?

Thank you for your help!

Regards,
Calvin
