Replacing VCSA while keeping history and configuration.

I have experienced some management issue with our current 6.0 U3b VCSA as well as services on the VCSA reporting errors. I want to move forward with deploying a fresh appliance but wish to migrate the existing appliances vPostgres database over to retain my configuration and historical data. I found VMware KB which explains the process of backing up and restoring the database but have some additional questions.

1. Does the replacement VCSA need to have the same hostname and IP Address?
2. Once the vPostgres database is restored, do i simply power off the old VCSA? or should i log into each host individually and disassociate them from the old VCSA and register them on the replacement?

1. Yes
2. Power off the old VCSA after you have the db to restore later. When you power on the new VCSA, it will reach out to hosts, and update their Agent.

@ Andrew Hancock. Thank you for the quick reply. What's disturbing is i asked HP (our VMware support is via HP) yesterday if i needed to change the new VCSA name and IP  to match the production VCSA since i've already deployed the replacement but its powered off and they said "no". Obviously that answer didn't sit well with me.

your database is not going to match!!!!

I would keep everything the same....

VMs will still continue to function, with no vCenter Server, do you have a simple environment ?
Need More Insight Into What’s Killing Your Network

Flow data analysis from SolarWinds NetFlow Traffic Analyzer (NTA), along with Network Performance Monitor (NPM), can give you deeper visibility into your network’s traffic.

You're absolutely right. Maybe the HP engineer didn't understand the question or my objective?

Not really sure what constitutes as simple?  We have 4 hosts divided across two separate DRS/SDRS/HA enabled clusters, we utilize resource pools and have datastores presented from 3 Dell EqualLogic arrays and a Nimble AF1000.

Standard Switches, No VDP, vSAN, SRM, VRA, NSX ?
grahamcoAuthor Commented:
I'm using both standard switches for the vMotion network, ESXi Host Mgmt and where needed iSCSI and Distributed switch for VMs. No i use vRanger not VDP for backups. I didn't see the benefit of vSAN given we have no local storage on the hosts, the disks in the EQL arrays are all the same in terms of speed and capacity. No replication being done currently, too costly for our organization.  I need to do some more reading on NSX to determine if it has a place, admittedly i know what it is conceptually but not from actual playing with it.
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Okay, so you are using Distributed Switches that need a little more care, with vCenter Server (VCSA).

So re-install using same name and IP Address, restore database.

Andrew is it necessary post-db-restore to integrate the replacement VCSA with AD, select administrator group,apply license,etc. or will all of those settings be applied after the database restore?

Should all be in the db.
