After installing the latest version of NetBeans I found that my old plugins were not migrated. I did the following to migrate them:

Run the new version of NetBeans and tell it to import my old stuff. Then close it again.

Copy the modules directory in ~/.netbeans/ to ~/.netbeans/

cp -avn ~/.netbeans/<old version>/modules ~/.netbeans/<new version>

Copy additional items from ~/.netbeans/config/Modules

cp -avn ~/.netbeans/<old version>/config/Modules/* ~/.netbeans/<new version>/config/Modules

That did the trick for me though it might not always work depending on the version you are migrating from and to.
