I have taken the plunge and am converting from ver 2.8.16 to ver 3. I used the .DUMP method but found a problem. My char/text fields containg numbers were output as pure numbers without the quotes, so that on input to ver 3 they were stored as integer rather than string. This is a kind of bug in .DUMP. Maintaining the textedness of values in columns with text affinity in ver 2 would ease the move to ver 3.
