Hi,
This question is very advanced and detailed about WLSDM usage
Yes, import feature is only available at wizard page and only available for the first installation. Wizard status property is available at “WLSDM Console > Left Menu > Configuration > WLSDM System Settings > system.wlsdm (TAB)” section. When you change the value of “system.wlsdm.wizard.completion.status” property value from 1 to 0, after restarting AdminServer; the wizard would be visible again. Yes, you can import another domain’s exported WLSDM configuration without any problem. But remember; this usage is recommended for advanced users.
I am recommending before doing it;
- Take a backup of your current WLSDM configuration; the button is available at “Configuration > WLSDM System Settings” page.

-
Take backup of your current config.xml file which is available at $DOMAIN_HOME/WLSDM/config/config.xml
-
If you have any problem while wizard and you are unable to complete WLSDM wizard with the imported config; Just shutdown WebLogic AdminServer; edit config.xml file by rollbacking system.wlsdm.wizard.completion.status from 0 to 1. If you exit without save your current configurations should be kept.
I just wonder; why you need to do that?
If you don’t have much configuration or important data available for the relevant WebLogic domain; I am recommending you, trying re-fresh installation. https://wlsdm.com/docs/README#IX.Upgrade&Reinstall&Uninstall
Just shutdown AdminServer; delete $DOMAIN_HOME/WLSDM runtime folder; then start AdminServer again. This time the wizard still would be visible then you can import your WLSDM configuration again.
Hope these would help.
Regards,
