Many of us here use Calibre.
What I'd do in your situation is connect the phone to my PC, copy all of the books from the phone to my PC. Then drag all of the books into Calibre. Then connect the Kobo to the PC and tell Calibre to send them to the Kobo.
Thereafter whenever I buy books or get ones from the library I'd first put them in Calibre and from there put them on my phone or Kobo.
