Can Smarter mail 12.3.5318 be directly upgraded to the most current build of the product, without doing the majors to get it to 15, then to current. The major/minor upgrade document does not seem clear on this due to the age of the installed version 12.3.5318. Host box is Windows 10pro 22h2 with framework 3.5 and 4.7 with current patches applied.
