Any risk to upgrade the exe from 3.0 to 3.7 is their any effect on users, data, permissions …
Not as long as You use latest hotfix of 3.70. If SQL You will probably have problems with field names in some views if You just open the old database and chose Yes to convert. This is because the change of language in these views. If You restore a backup You wont have this problem.
I believe there are instances where problems can arise. I know that if you have used SETFILTER(field, value) where the value is larger than the MAXSTRLEN(field) you will now get a run time overflow error where as before you didn’t. This is the only issue I’ve come across. Regards, Alex
