32bit application check for upgrading from x86 W2K3 to a x64 O/S
I have a task to upgrade our remaining W2003 virtual machines to W2012 some of which are x86 versions.
I understand x64 O/S provides syswow64, an emulator that enables 32 bit applications to run. Sounds good in theory but has anyone experienced issues running 32 bit apps on x64 O/S after upgrading. Short of contacting application vendors for compatibility issues are there any tools available to check for compatibility prior to upgrading.
Many thanks in advance

The tools available are the Mk1 eyeball and a test VM where you can run the apps you intend to install on the server to see if they work. Most of the time there should be no issue but it is not impossible that your app installers may be configured to check the windows version and not install if the version is outside the range they were originally designed for. Only actual testing will confirm operation in your environment, as vendors may not be able to clarify compatibility with X64 in an absolute sense.

Additionally, many vendors will tell you that their applications are "not compatible" with 64-bit OSes. What they mean is either "We haven't bothered to do proper testing" or, more usually, "We have a 64-bit-capable version to which you can upgrade by divesting your company of 80% of its tangible assets."
Use your VMs to set up a lab and test, test, test!
