Upgrading

Using backends from an earlier version

The simplest solution is to copy each backend folder in the Backends folder in your previous 3di installation to the Backends folder in your new installation. If the new and old 3di installations are not on the same machine you can copy the required backends folders via a USB key. Copying rather than moving backend folders is strongly recommended since it means you will have the original backends as backups. You will not be able to copy a backend into your new 3di installation folder if you have already created a new backend with the same name.

If some reports for children in your imported backends don’t run, just open each interview from the new installation and immediately close it – that way each child will be endowed with unanswered copies of any questions which are new in your new installation.

If your new installation has dropped some questions that were active in your old installation they will not appear on the interview forms and will not be reflected in reports from the new installation.
