Linking old interviews from Crashed server to a new one

My server crashed last week, I need to know if it is possible to link back the tablets with the newly installed postgre SQL database.
Again Is it possible to extract data(from crashed database) from the tablets.

Restore database from the latest backup.
If it’s recent, the is very high probability that everything will sync without issues.

There was no backup that is why I created a new platform all together.
No backups because the whole server crashed

@smfoulo, first, see my response in the other thread:

To the best of my knowledge the tablets will not be synching with another (blank / new) server, even if you give it the same name and create the same account name/password for the interviewer account. The information that is needed for the synchronization to work is (was) in that database that you’ve lost on the crashed server.
