[Pki-users] Backup/restore of Dogtag servers when migrating FC15 to FC17

Hi all, I was looking at migrating the OS I run the CA, RA and OCSP on from Fedora 15 servers to Fedora 17. I saw the section in the admin guide relating to backup/restore (sec 12.10 in the 8.1 guide) and wanted to know if this approach will work when the restore is happening on a different target OS than the source OS (i.e. FC17 from a FC15 source). Has anyone tried it? Any pitfalls I need to be aware of above and beyond the stuff outlined in the documentation? Thank you, Jamil
