I’m not 100% sure how to do that…but I can try.
Can I ask a ‘general’ 8.0 Dbase question?
Are there any DBase changes from 7x to 8x?
If I want to migrate to a ‘fresh’ 8.8 install, can I ‘move’ the 7x Dbase into the 8 Dbase without changes? (Or are there some structural Dbase modifications required?)
I would definitely not advise that, just use the migration script that takes care of everything for you.
