recovery windows live mail db on new computer

Hi,

My problem:
situation:  a Vista HomePremium computer could not started regularly anymore.
                I could make a complete copy of the user directories. In meanwhile HDD is broken.
                WLM 2011 was used under Vista. WLM 2012 will be used on new Win 8.1 computer.
 
question: is there a way to recover the messages, contacts, calender from  the saved WLM 2011 folders under WLM 2012?

               (...user\AppData\Local\Microsoft\Windows Live Mail )
I found somewhere here a solution for contacts on WLM  same version.
But I do not have a Vista computer available any more.
Or can this be done only by a 3rd party tool/product?

Thank you for  your help in advance.
Sigi
