There has been some recent news on this. The migration hit some problems and it is not complete. Google is working on their migration tool to fix the issues and presumably they will run the migration completely once that is done.
Google Earth team (April 4):
We are still working to migrate the photos of those Panoramio users
who linked to their Google+ profiles. We are detangling some
oversights in the transfer tool’s original design and need to take our
time in order to do it right. This has taken far longer than
originally expected, so we sincerely appreciate your patience.
Once the migration is complete, you should see an improvement in the
coverage and availability of photos in Earth, especially in
out-of-the-way places. More on that below.
I can currently see my Panoramio-uploaded photos on my Contributions screen of Google Maps. You should be able to see yours here - https://www.google.com/maps/contrib/
To find it, just go to Google Maps, make sure you aren't viewing any particulary place and don't have anything searched, and then use the "hamburger menu" (three horiztontal lines), and then click "Your contributions".
You have to be logged into the Google account that your Panoramio account was linked to. I believe that Google account also had to be Google+ enabled. Chances are it was.
However, if you click on a photo here, the map view on the right kind of flies down to the ground and then just shows a black screen instead of a larger image. Google is aware of this problem, but I think it's related to the migration issue.
None of the Panoramio photos show in Google Earth right now. They did fully disable the layer, and only the little icons show at the locations where Panoramio photos existed. The server holding the actual images that displayed from Panoramio photos layer in Google Earth is gone.
Google Earth team (April 6):
Further clarification: We can’t bring back the Panoramio layer There’s
no way to bring back the original Panoramio layer. The Earth database
we use to display the points on the map contains the locations of the
original Panoramio photos and just a reference to the original photo
URLs. However, that database is separate from the server that hosted
the Panoramio images themselves. That server has been taken down, so
those URLs aren’t valid anymore. This is why we put the notification
message in all the balloons and offered people a way to turn on the
new Google Maps Photos layer.
We have to wait until the eligible Panoramio photos are migrated into
the new catalog (and hosted under their new URLs) before we can
include them in the new Photos layer.
I think they will show within the new Google Maps photos layer in Google Earth once the migration has completed.

I encourage you to go to the link above and watch for progress, and also help shape the future functionality of Google products regarding photo layers for Google Earth and Maps, and uploading of geolocated photos. I think Google can build in features to bring Maps closer to the great functionality Panoramio had, but we need to nudge them that direction. Google did hear users when lots were upset about the disappearance of Panoramio photos, both because Earth users missed the great photos layer, and former Panoramio users missed the fun of uploading a mapped photo.
