Hi, after some research and test i found the correct solution
1) Backup all Windows Vcenters
2) Migrate vcenter-A from Windows to VCSA-A with Embedded psc 6.7U1
3) on VCSA-A run cmsso-util domain-repoint to change sso domain name to sso-def.local
4) Migrate vcenter-B from Windows to VCSA-B with Embedded psc 6.7U1
5) on VCSA-B run cmsso-util domain-repoint with replication flag to set replication partners as VCSA-A and domain sso-def.local
6) At this time the Embedded Linked mode should Works
7) Activate vCenter HA on VCSA-A
😎 Activate vCetner HA on VCSA-B
9) Reconfigure SRM to repoint a new vcenters with embedded psc
Do you confirm the procedure?
Best regards
