I would like to ask for some idea and help on what and how to reorganize our vsphere infrastructure.
We have an environment that grow really fast in the last 2 years... from a single vcenter center/infrastructure for our server environment we growth to 2 main Datacenter + 1 small site with a 2nd arriving in some months and probably a good number of branch offices.
Our 2 main datacenter are configured each with 3 vCenter 5.5:
1) Our Main Server vCenter
2) Our Horizon vCenter for VDI
3) A vCenter dedicated to a separate set of servers for a specific project
All the vCenter are now 5.5u2 but in the past our VDI vSphere was still 5.0 while the rest was upgaded to 5.1 and then 5.5.
The 3) is a dedicated environment with some software/configuration that could conflict or be managed in a different way from our actual infrastructure (it could remain to an older version for more time for example).
All those vCenter are configured with a Multisite SSO separated by environment so we have a Multisite SSO for Server, 1 for VDI and 1 for the 3).
Our vCenter have the SSO and all services embedded into the windows server and a separate SQL Server Database for each of them.
Checking some documents on the vSphere 6 I saw that it seems that we've a configuration that should in some way changed and thinking about the future and implementation of new products I would like to understand how we could manage those infrastructure and how we can join it.
In this document http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2108548 it seems that managing sites that have embedded PSC and vCenter Server on the same host is not a recommended configuration so, thinking at least at our main Server vCenter infrastructure (2 different in 2 sites) we should separate the PSC making them external.
Should we move the SSO server outside of our 5.5 infrastructure now before upgrading to 6 so that we could upgrade SSO to external PSC and simply upgrade our vCenter Server or there's any way during upgrade to put the PSC on an external server (like running the setup on a new server and migrating the SSO to external PSC)?
Thinking about the future, we would probably like to unify the PSC and use the same PSC servers (2 ha with a LB probably in each site). It's possible when upgrading a vcenter Server to migrate it from the SSO server/PSC it's using to a different one?
