Hi Lynn,
 
I am needing clarification. As far as the technical support, if an upgrade takes improperly or something else were to happen with DBA, will DBA tech support have problem with dealing with a problem that me stem from an IS Tech upgrade. That is if you still have DBA support time. I understand your company, but I need to expalin it to my plant manager who approve this type of transactions.
Thanks......

Before you can apply any ISTS updates, you need to get your DBA updated to version 2002.4.  That version is a straight DBA update and any issues involved with applying that update can be resolved with their technical support although ISTS can help too if you are a support subscriber.
 
Once you are on 2002.4 and begin installing ISTS updates, you can tell whether any program has been modified by ISTS by looking in the top margin of the screen when you are in the program.  If it is a straight DBA program, it will say something like "GL-F Print Financial Statements" in which case you could get support from DBA although ISTS will also support the DBA programs.  If it says something like "SO-B Print Acknowledgements - ISTS Enhancement 2/28/03" then DBA will not help you and you need to contact ISTS.
 
As for installing future updates, once you are an ISTS subscriber, it is recommended that you always install updates from the ISTS site.  Our updates will always include anything released by DBA.  Ever since 2002.4 was released, DBA has taken the stand of not making any updates to the TAS 5 version of DBA other than essential bug fix patches and those patches will always be included in the ISTS updates.
