You can copy your batches, which are located in C:/Program Files/Vendio/batches.
You may do the same with the inv.dat file (located in the Data folder), which will copy your existing inventory listings (be sure to copy this to the Data folder in the new installation.) Please do not attempt to copy the profile.dat file as this may cause problems.
The safest way to copy your images into the new Pro version is to synchronize, although you may be able to successfully copy the images from the Images folder in the old directory into the Images folder in the new directory.
