Hi Team,
We have just upgraded the ArcGIS Entreprises along with the add on server. We have upgraded the Mission Server also from 11.0 to 11.1
When I open the missions created in the previous version (11.0) getting this message "This mission was created in a previous version of ArcGIS Mission and can not be opened in this version."

But I am able to create new Mission.
Please help me to solve this issue.
Regards,
Sunita
