the code on this 2 file should be changed:
under the directory /usr/lib/vmware-vcops/tomcat-enterprise/webapps/vcops-custom/pages
widgetGeo.jsp
pickerGeoLocation.jsp
the lines:
<s:if test="%{googleMapKey != ''}">
<script src="https://maps.google.com/maps?file=api&v=2&key=${googleMapKey}" type="text/javascript"></script>
</s:if>
shoud be:
<script type="text/javascript" src="//maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&key=API_KEY&language=de"></script>
as described in
https://developers.google.com/maps/documentation/javascript/v2/v2tov3
but it's not enough 
..
Hi
i mean that it doesn't work
i've found another file to modify in the same directory ..and is the environmentOverview.jsp file.
Now the situation is that i don't get the API V2 error anymore, but the Google Map CHart is blank!
yes sure only line to be modified is the <script one
this is the replace string:
<script type="text/javascript" src="//maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&key=${googleMapKey}"></script>
UPDATE:
well there are a lot of things to change..that only the developers can do...
you need to change your code to make use of the new namespace
for example Gmap2 now is google.map.Map
Ok, error messages disapears and "Manage location" button in the Manage Resource Tag Window is now there, but no maps, just whitespace 
I'll dig deeper....
