I am testing a distributed vCenter VCSW v5.5U3 to VCSA 6.5U1e migration scenario before attempting it in Production.
I have 5 Windows 2008 R2 servers in a distributed vCenter v5.5 configuration. Reasons behind this config need not be debated here - this is the situation I have to deal with.
MC-VCSW-V-201 Role - vSphere vCenter Server
MC-VCSO-V-201 Role - SSO & Inventory Service Server
MC-MSQL-V-201 Role - External SQL Database Server (SQL 2008 Standard R2 SP2) (VC & UM DB's)
MC-VCUM-V-201 Role - vSphere Update Manager Server
MC-VCWC-V-201 Role - vSphere Web Client Server
I understand the distributed migration sequence is SSO->PSC first and then VCSW->VCSA second.
I started the VCSA 6.5U1e Migration Assistant on MC-VCSO-V-201 and it fails with the error:

2018-03-02 20:59:24.944Z| migration-assistant-7515524| I: GetJsonProperty: Json was: Warning: Following extensions are installed on this machine along with VMware Single Sign-On 5.5: VMware vCenter Inventory Service 5.5.0.45995 This machine will be shutdown as part of the VMware Single Sign-On 5.5 migration to Platform Service Controller Appliance 6.5, and the above listed extensions will stop working after the shutdown. move the above listed products to a different machine, and re-launch Migration Assistant to migrate your VMware Single Sign-On 5.5 to Platform Service Controller 6.5. |
My question is "How do I move a vCenter Inventory Service component from a working vCenter without breaking something"?
The VMware Docs article Distributed vCenter Server 5.5 for Windows Services Relocation During Upgrade or Migration does not mention this being an issue!
Any advice is welcome.
Thanks.
