windchill 13.0 index searching not working

Hi there,

after successfully Installing Windchill 13.0 including working Solr-Server and working “search” within windchill, I migrated my data to that new location.

all issues in upgrademanager were solved successfully.
I can accesss my files and all data is shown. 
I even can checkout files with Creo Parametric and check them in again.

But Indexing does not work at all. 

Solr - Server is running. I can login via http://localhost:8085
Credentials for solr are set in Windchill via 

xconfmanager -s wt.index.solrAdminUser=<User> -t codebase/WEB-INF/conf/index.solrAuth.properties -p
xconfmanager -s wt.index.solrAdminPassword=<Password> -t codebase/WEB-INF/conf/index.solrAuth.properties -p

But queue is not starting.
The number of “remaining items” is stuck at 20k+ items, the number of processed Items is stuck at zero
( Site → Utilities → Indexing Administration ).

I tried “windchill wt.index.BulkIndexTool” in windchill’s hell and I got this:

Core 'wblib' is selected.

For the records: There is no working “CAD worker” yet.
