Ax Upgradation from 2009 SP1 to 2012 R3( Data Pre-Processing )

Hi Mates,

While I'm working on upgrade of Ax 2009 to 2012 R3 . First step is Data Pre-Processing, where i got some Validation errors in DataUpgradeCookpit regarding to LedgerJournalTrans Table. 

Because some JV Lines are Posted with "Account Type" and "Account Num" Missmatch and Vice Versa

(Ex:AccountType-Vendor,AccountNum-4220001  & AccountType-Ledger,AccountNum-V_02222)

4220001 - G/L Account 

V_02222 - Vendor AccountNum

All these Transactions has been Already Posted & we are unable to port the transactions from 2009 to 2012 r3.

My Question how come system allowed this Transaction to post without validating ?

Like this we having 700 JV Lines posted . Please Advice. Thanks in Advance
