I have a SharePoint 2010 User Profile Service Sychronization service that has acted up in the past and now I find that it's flat out refused to start. I did some investigating and found that somehow the User Profile Service service application has lost its Synchonization connections; there are none showing up in the Synchronization connection list. I plan to do the following:
- Delete and recreate the User Profile Service service application using the current UPS databases.
- Create a new synchronization connection.
I don't want users to lose their Mysite data. My question is, if I recreate a new connection, will this affect the current users' data?
