I have installed MS Project server 2013 and Integrated it with MS SharePoint 2013
and I created a Project Web App with SharePoint permission mode.
Now I want to Change from SharePoint Permission Mode to Project Server Permission Mode
In Microsoft Site it said that if you change from SharePoint Permission Mode to Project Server Permission Mode it will delete all security groups.
I did not understand it would it delete all security groups related to this Project web App I created or it will delete other sites collections security group also.
