R3 Data restore to R2

Hi Guys

i have an Ax2012 R3(Sql Server 2008) data (.bak )file and i want to restore that data into ax2012R2 (sql server 2008)

i didn’t do any customization on both environments is it possible, please help me out

No, the database schema isn’t the same. Either use a dataset for R2 or install R3.

If it is not possible at which situations i can restore backup exactly – is kernel versions must be same?

Don’t try to use data sets for different releases. Hotfixes usually don’t make difference.
