We have a client on 3.71 that we are trying to upgrade to 2013. In the test run of their upgrade we have run into a situation with 7 GL balance sheet accounts that came over to v2013 with difference balances than in v3.71. The GL Trial Balance is still in balance as the offset went to Retained Earnings for these 7 accounts. In researching these accounts in the v3.71 instance I have found that in historical years (2007-2010) there are differences in the year end ending balance and the following year beginning balance. Has anyone run into this before and know of a fix to correct in 3.71 prior to migration?
