This is what I've sent internally just recently - hopefully it will help some people here:
I think we've all had various credit card conversion errors with the 2013 upgrade over the last few months, whether the client is using Century Business Solutions' eBizCharge, or Sage Payment Solutions, or no processor at all. I've been encountering errors on multiple upgrades lately and I believe I have some steps that might help with both the test and the live upgrades. Of course, you may not be getting the same errors I am, but hopefully the info I have here will help in some way.
If the client has CBS's eBizCharge program, I've been getting an Error 65 CI_SageExchange error during conversion. After talking with someone from their engineering dept last week, I've been able to get through that particular error by reinstalling all stock Sage 2013 program files and product updates, and any 3rd-party programs EXCEPT for eBizcharge. Remigrate data only and convert. CBS claims that they have a conversion program that will put all credit card information from the old system into the eBizCharge vault after the conversion is successful. I've asked for that program and instructions to run it, but haven't received anything yet. More than likely, they will need to get connected to the server anyways to install the program and enter/confirm setups anyways, so make sure they are scheduled well in advance, since support is tough to get in a time crunch with them.
Regardless of the processor the client has, or if they do not process payments but maintain credit cards, I also have encountered an alternating Error 13 and Error 80 during conversion. In my experience so far, I have found Error 12 records within the ..\MAS90\MAS_XXX\05.00 Company Data Conversion Log which indicate files are missing, followed by the Error 13 you see on the screen. It is looking for some *_orig.M4T files that are not being automatically created by the conversion, so once I created them manually, my conversion went through. What I did is I made copies of the following files:
AR_CashReceiptsDetail
AR_CashReceiptsHeader
AR_CashReceiptsHistory
AR_Customer
AR_CustomerCreditCard
AR_DepositHistory
AR_InvoiceHistoryHeader
AR_PaymentType
AR_TransactionPaymentHistory
And appended them with an _orig, like so:
AR_CashReceiptsDetail_orig
AR_CashReceiptsHeader_orig
Once the conversion is completed, those files are removed by the conversion process.
I asked Sage why the program is not creating these files successfully, even though my directory has Full Control permissions, and they believes it could be due to anti-virus settings, so who knows yet. Engineering also claims that there is no known risk to creating these files manually if needed.
