Approving this operation might cause data corruption if both Data Centers are active. How can I detach this domain to a non visible old Data Center ?? Can I pass this alert without data lost ?

So I have backups from the previous Manager, I can backup to the new one. But, reading the overt-engine-backup, it seems to be possible only before doing engine-setup. Is that right or may I launch a backup after an engine-setup ? An engine-clean is enough to use engine-backup ?

You have basically two alternatives: A. backup the DB and restore it on the new engine as described here: http://www.ovirt.org/Ovirt-engine-backup B. Start from scratch with a new engine on a new DB and re-import existing storage domains: http://www.ovirt.org/Features/ImportStorageDomain Option B involves a lot of manual steps but it could be also used as a disaster recovery flow when the DB is for any reasons lost or corrupted. > Alain VONDRA > Chargé d'exploitation des Systèmes d'Information Direction > Administrative et Financière > +33 1 44 39 77 76 > UNICEF France > 3 rue Duguay Trouin 75006 PARIS > www.unicef.fr > > > > > _______________________________________________ > Users mailing list > Users(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
