Try the following:
Export---From the old system
1) Export your globals in file MyGlobals.gof
Management Portal->System Explorer->Globals->Select Globals->Export->FileName->Export
2) Export your classes in file MyClasses.xls
From Studio Editor-Tolls->Export->Export to Local File->MyClasses.xls->Add->Select Clasees->Add
Import---In the new system
3) Import your globals from the file MyGlobals.gof
Management Portal->System Explorer->Globals->Select your namespace->Import->Select FileName->Import
4) Import your classes from file MyClasses.xls
From Studio Editor-Tolls->Import Local...->Select File Name->MyClasses.xls->Open->OK.
Although when files are imported, they are compiled you must recompile them again starting with subclasses-firtsly-
like Titles, Components, Composites etc., and after that the main classes.!!!
(For small datebases do it manually-From Studio Editor-> Select the class(double click)->Right button click->From the popup window- Compile..)
With this procedure I hope you will not have any problems.
