Problem with updating BC V16.5 to V17

HansF

After Update from version BC16.5 to V17.0 Application Database Version is still V16. All steps from the documentation are done. After update the webclient starts, but from the development environment i cannot publish my extension because of the Application Database Version V16. Synchronisation is done. Navdataupgrade is done. The Application Version is still 16.5.15897.15953. If i try to set the Version with Set-NavApplication i got the following error:
Set-NAVApplication : Die ApplicationVersion 17.0.16993.0 ändert einen Teil der Version außer „revision”.
In Zeile:1 Zeichen:1
+ Set-NAVApplication -ServerInstance Dev170 -ApplicationVersion '17.0.1 ...

+ CategoryInfo : NotSpecified: (0:Int32) [Set-NAVApplication], FaultException`1

Is there anybody who knows about this issue?
