Hello All -
I am in the process of considering an upgrade from v9. I downloaded the trial version of 12.5.2, migrated the application and tested. The application has about 10 PBL(s) with a SQL Anywhere v9.0.2 backend connecting via odbc. The application has been extremely stable for years on version 9. We are in the process of performing some additional development on the app and think this would be a good to time for the upgrade. Anyway our testing of 12.5.2 was great everything checked out so we purchased a 12.6 license. I installed 12.6 on win7 32bit VM and licensed the install. So to continue our testing we migrated the code to 12.6 and installed for testing on the same machine (win 2008 R2 TS machine) we performed the 12.5.2 testing. We cleaned the machine of the 12.5.2 install prior to installing the 12.6 version of the app. Well testing has not went as smoothly as it did with 12.5.2. So far I have two windows where when we click on a datawindow within the windows the application crashes. I have only found two windows so far that exhibit this behavior. All the other windows (that I have tested)work fine. The good news is the problem can be duplicated on the development machine. However, so far I have been unable to locate or trap the error in debug mode.Meaning I have not been able to located the faulting instruction so far. So I have a couple questions.
1.) Can I install 12.5.2 on the same machine as 12.6? Will this be licensed correctly? My reasoning here is if I can get 12.5.2 successfully migrated and tested we may chose to deploy as a 12.5.2 and move to 12.6 at a later date after this round of development is complete.
2.) Assuming question 1 is true - Are all builds of 12.5.2 stable? Any that we should avoid?
3.) Lastly and move obvious - Any insight as to why the datawindow may be causing a 12.6 version of the app to crash where a 12.5.2 version worked fine?
TIA - Jason
