At least by design, old programs can handle current binary files. The binary files include an old (32-bit) representation of the source files, followed by a new (64-bit) representation. (Back at the start of the project in the 1980s, time_t values were 32 bits; as they grew to 64 bits, the binaries were expanded to cover the bigger time_t range. Old programs, as well as 32-bit programs, ignore the 64-bit data.) @dashdashado On Tue, Apr 28, 2015 at 5:19 AM, Thomas v. Karlsson < thomas.v.karlsson@se.abb.com> wrote:

Hi,

I would like to know the compatibility constraints between the code and the datebase.

Is the code forward and backward compatible with the database binaries? I.e can code read older and newer version of database binaries?

Or do the code and the database need to be version sync with each other?

Thanks
