• After a bulk certificate import, a migrating phone asks its home (source) cluster's TVS to validate the destination cluster's certificates before it accepts the destination ITL. in context
• Bulk certificate export, consolidate and import are done under Cisco Unified OS Administration > Security > Bulk Certificate Management. in context
• Before a bulk certificate migration, Prepare Cluster for Rollback to Pre 8.0 must be False on the source cluster. in context
• Bulk certificate migration order: export the destination cluster's certificates to SFTP, export the source cluster's to the same location, consolidate once on one cluster, import into both clusters, then point the phones at the destination TFTP and reset them. in context
• Bulk certificate management for phone migration needs an SFTP server reachable from both clusters, where the exported PKCS12 files are stored and consolidated. in context
