Missing Data Issues (Re-Run 2.7 to 3.0 Upgrade)

[srodee]

I used the app all through last year (2015), recently went through a divorce and was forced to start my own apple ID, i cannot figure out how to get the information off of my old apple ID, nor do i know how to check for original date of purchase, but i do believe we were using the paid version at the time. Is there a way for me to get that information back? it has all of the data from my car from the day i bought it.
My old Apple ID was scaudra@gmail.com and it was for a 2012 suabru outback 3.6r
