[Theme problem] Upgrade from 1.3.1 to 1.6.0.9

[blank_screen]

I've been doing some upgrade tests on a localhost using WAMP following the step by step Manual Update instructions on Prestashop website. Now, the local upgrade went smooth and all worked fine apart from the theme, which is slightly altered. I know the theme from 1.3.1 will not work well on 1.6.0.9, I was fully aware of that before even starting the upgrade and I didn't really like the old look, so I began to change the default-bootstrap theme, when I was happy I copied that folder with a new name into themes folder but after upgrade I have to repeat some customisation steps again like for example transplanting hooks or turning on or off some features etc. Is there a way that after upgrade I can just pick the ready made theme from the back office menu not having to customise it again?

 

Thanks in advance for any help.
