IntelliJ - Import configuration from old version after first run

Solution 1:

Starting with IntelliJ IDEA 2020.1 the settings are imported automatically from the most recently used previous version and the dialog is not shown.

To start with the default settings you can use File | Manage IDE Settings | Restore Default Settings.

Also note that default folders used by the IDE have also changed since 2020.1 release.

Original answer for older versions:

This dialog is displayed only when there is no existing directory for IDE configuration of this version.

In your case there is probably %MY_HOME_DIR%/.IntelliJIdea2017.2 directory already created if you were using EAP or RC builds before.

Removing IDE configuration directory will display this dialog again on the next start.

As of version 2020.1, Jetbrains has changed the directory where preferences are stored.
