Answer / dave
Parallel Testing is where you have 2 environments that are
identical. One is live and the other is used for testing
purposes. You would install your upgrade, new build or new
application on the testing environment and run it in
Parallel with your live environment to see if anything
breaks. If your testing environment passes, then you can
install the upgrade, new build, or new application on your
live environment. Your testing environment can be
installed using VMWare to save on cost.

Answer / jorge
Parallel testing does not necessarily mean the two
applications have to be identical.
This is something that was valid long time ago.
The new modernized application might have enhancements that
make them not 100% mirrored.
However, you still can run a Parallel test on the two
environments with same feed data, and get the results to
compare the outputs.
If the new application has enhancements or streamlined
processes, then you will need to be aware of their
nature(i.e some fields in the modern app might display a
flag in a different format, numbers could display a
different aggregate result, data migration process could
change values from legacy to the new database based on the
new field definition, some old fields might be declared
obsolete and not migrated, etc.), but that does not mean you
can not compare the results of both outputs.
They will require a more exhaustive analysis to declare if
they pass the testing.
Today is not possible to be so simplistic to assume that
Legacy and Modern application will be 100% identical in all
their batch processes. Knowing what parts and where the
software implementation differs, will enable you to still
run a parallel testing and evaluate the validity of the
results.
Nowadays parallel testing is about evaluate the correctness
of the results,and not to expect identical results in all cases.
