Most valid Ada 83 programs are valid Ada 95 programs with the same
semantics.  Most of the exceptions (such as using new keywords as
identifiers) are easy to fix.

Try compiling the application with GNAT (or with any Ada 95 compiler).
You're likely to run into more problems going from one compiler to
another than going from Ada 83 to Ada 95, especially if the program
uses any compiler-specific features -- and you're going to have to fix
those problems anyway.

Since Ada 83 compilers are, for the most part, no longer being
maintained, you might not be able to find one that works with a newer
operating system.
