Upgrading SEPM v.11 to v.12

Hy everyone,

I'm upgrading Symantec Endpoing Protection Manager version 11 to version 12.

I have did a database backup before uninstall the SEPM version 11.

Now I ahve installed SEPM version 12 and I'm restroring backup to the new SEPM version 12.

My question is:

- What is the database backup contains of?

- Is it possible to restore version 11 backup to version 12 SEPM?

- All clients that has been added to the group on version 11 will be remain after the restore process?

Thank you for your reply.
