It DataEase 8.0 Is compatible with Windows 7 and later? Can run application developed Datataease DataEase 6.52 to 8.0? Same question for DataEase version in Spanish Thanks.

DataEase 8.x is fully compatible Windows 7.x through Windows 8.x and is currently being tested in Windows 10, so far without any problems.

You can migrate any DFW 6.x application to DFW 8.2 or later. It will in most cases be completely straight forward, but there is a couple of things you need to bear in mind:

1. Extended characters.

If you have used extended characters in your tables, columns, derivations there might be conversions issues between 6.x and 8.2x. We are currently looking into this and will soon publish an updated including different translations for successful migrations.

2. Base year
Make sure you set the base year in your DataEase 6.x application to 75 before you start.

3. Date Format.
Do not select from Configuration. Select the correct format you have used ex. Dd-mm-yy. If you get a lot of trouble in migration with illegal date it is due to either 2 or 3. Just change the settings and try over.

We re-introduced Menu documents and old Style memo in DE8.2 so it should be a 1 to 1 migration, but as with all migrations there might be situations and code that is not covered.

With DataEase 8.5 we for the first time since 7.0 have a version of DFW that vastly outperform earlier DFW versions so there should be no reason to hold back due to the earlier experienced performance problems identified with DFW 7.
