Need Help moving accounts from one server to a new cloud VPS No root access just Admin reseller

[mixcat]

Hello guys,
I need some help moving all the accounts from my current server that doesnt have root access but an Admin level reseller to my new VPS cloud with Root access..
The xfer option isnt availible on my current server and the support is less then helpful.
I have 54 accounts on the server and im thinking they have to be moved one by one.
I would love to get some help with this.. Please let me know if its something you can do and what you would charge me for your help.
Thanks so much.

I forgot to add that I have sftp connection on the old server with backups but the file extension is txz if that helps.

Hello

How were the backup archives generated? Are they valid cPanel backup archives? Note that you can copy over accounts one by one using the following option on the destination server:

"WHM Home » Transfers » Copy an Account From Another Server With an Account Password"

Thank you.
